Completion bonuses
Successfully complete the game to unlock Ragnarok in local multi-player 
mode. Successfully complete the game on any difficult setting to 
unlock a mech called Ymir. Note: The Ragnarok mech is a perfect 
blend of armor, firepower, and heat design as long you do not use 
the lava gun constantly. The Ymir has greater firepower than the 
regular chassis of Ragnarok. However, it generates a great deal 
more heat, making it a good choice for advanced players for to make 
short work of their opposition.
 
Avoid PPC projectile
To easily avoid a PPC projectile when playing on Xbox Live, choose 
a mech that has jump jets. While the enemy is charging up their 
PPC, activate your jump jets. Once they fire, release the jump jets 
and the PPC will fly over you as you fall to the ground. This can 
be very effective against Mad Cats.

Cloaking
To walk in the water without kicking up water behind you, simply cloak (turn 
invisible) while you are in the water and wait until you are completely invisible. 
Then you can not be seen while walking in the water. 

You should entreat to walk while cloaked anyway, since running will cause your 
mech to appear in a faint outline. 

Unlock Ragnarok For Multiplayer 
To unlock the ultimate Ragnarok mech for online/multiplayer, simply beat the 
single player Campaign mode. The Ymir variant will also be unlocked. 

Easy catapult kill:
At the beginning of the level where you must kill the WOB's second in command, 
stay on the ledge. Do not fall or you will be slaughtered. Kill the stray Mech that is 
not one of the objectives. Next, walk further down the ledge until you reach a 
bridge. Use your radar to see when the objective Mech catapults are under the 
bridge, then blast the bridge. It should kill most of the Mechs. Then just finish off 
the survivors.

Using any Mech with high output energy weapons, go forward as fast as possible to 
the gate where the WOB second in command is headed. Take out any opposition 
along the way and ignore the Catapult convoy in the valley below. After 
eliminating any enemies along the way, power up health and weapons as much as 
possible and wait for the convoy on the other side of that first gate. If they do not 
come at first, you may need to engage them, then fall back to the gate and hold 
position there. If you position yourself at an angle, you can take out the whole 
convoy one Mech at a time with your energy weapon, while taking minimal fire 
through the opening of the gate. You have the wall as cover, protecting you from 
all but one Mech at a time, and the opening as your line-of-fire to take them all out 
one by one. The result is an easy low-risk kill with a huge pile of power-ups at the 
gate for you to replenish your health and weapons as you pick off each of the 
enemy Mechs. When you are done, power up and pick off the second in command. 
He should be alone in the valley.

Easy stats on Xbox Live:
Two controllers are required for this trick. Sign into your Xbox Live account from 
the Mech Assault menu. When you are ready to play, create a match of your 
choosing (Destruction, Team Destruction, Capture The Flag, etc.), but set the 
number of people in the game to two. You can do this cheat by yourself. When you 
ar in the team selection, mech selection, and skin selection room, make sure that 
if it is a team game that you are a different color from your guest (controller two). 
If its a game like Destruction, then choose a big Mech with lots of powerful 
firepower and have your guest control a weak Mech (like elemental). If it is a 
game like Capture The Flag, then choose a fast Mech and any desired Mech for the 
guest. Start the game and you can score points easily without worrying about 
being killed. Your stats will increase at the stats menu.

Easy Last Man Standing win:
Get at least three players. Hide, and then after everyone has killed the others, 
come back out and fight the last player that was standing.

Tag enemies with flares:
This trick requires you to be in a Mech that has a flare launcher. Get right up to an 
enemy mech (touching it), then launch a flare. It should stick to them. Any 
missiles fired from any enemy tank or Mech will hit the one "tagged." This also 
works on tanks, but they are smaller and faster.

Suicide:
When you play the game on Xbox Live, choose Host Game or Optimatch, then 
play "Last Man Standing". When you die, you will become a human. Click the Right 
Analog-stick and you will commit suicide.

Wall Walk:
To walk up the side of most steep hills, face the desired hill directly. Begin to move 
forward full speed and as you are about to slide back down, turn quickly to the left 
or right, then quickly back forward. This can be repeated but takes a little practice. 
Very helpful in multiplayer CTF for those runners without jump jets.

Listen To Your Surveillance Team:
These guys have the skinny not only on the mission objectives, but places to hit 
for bonuses and places to outright avoid. 

Watch Your Ammo Supply:
Yeah, those short-range missiles are pretty impressive, but save them for larger 
targets. You've got a really limited supply. The best plan is minimum firepower for 
maximum result.

Dodge, Cover And Run:
Don't walk into the line of fire, I learned the hard way. Use buildings and other 
structures for cover as often as possible. When you see those guided missiles 
heading your way, run like hell, and as erratically as possible. Sometimes you can 
shake them off and save yourself a world of hurt.

Smash Those Buildings:
Inside many key structures you'll find health packs and other goodies. This can 
mean the difference between a critical failure and mission success. Also, many of 
the buildings are spawn points for tanks and other nasties. Destroy the buildings 
and you'll have fewer opponents to worry about.

Keep Cool:
Heat is a factor that must be monitored. Certain weapons generate heat as you 
fire them, so once your weapon overheats it won't function anymore, which takes 
you right out of the battle. So you can use natural settings to get rid of heat, like 
jumping into a river.

Fit The 'Mech To The Mission:
Prior to each mission you can configure your 'Mech's weapons through a wide 
variety of options. But the really cool feature is the ability to do mid-mission 
weapon upgrades. Remember those smashed buildings? If you find a weapons 
facility building, bust it open. Inside will be bonuses such as a brand new Heavy 
Gauss rifle that can be installed right there.

Lava area:
When playing as the Atlas in the lava area, at the end near the party, do not go 
into the area from the cave too far. It will activate several Mechs including an Atlas 
or two. Instead, destroy the helicopters with ease, then start destroying everything 
around that gets targeted. Eventually, you will find two Atlases in the back left 
corner. You will know that you are targeting them because it takes a lot to destroy 
them. Note: you should not be able to see them. Inch forward from the opening 
and you should be fine. Note: You will face two mechs, a Madcat and a Belial. Also, 
the Atlases will not attack you in retaliation. 

Water walking:
When you are on any map with water and you have a mech with null sig, click the 
Right Analog-stick. When you do so, when you walk you will not make any 
splashes in the water. This is very useful on Xbox Live in the Jotenhiem map when 
approaching the red or blue base.

More Jump jet fuel:
When you have a mech with jump jets, fly in the air until you have three quarters 
jump jet fuel remaining. Then, release the Analog-stick and press it again before 
you fall. Continue to do this until you run out of jet fuel. You will fly up in the air 
for a long time. Note: Get on top of a building for more flight. 

Glide up a wall:
When jump jetting up a wall, press Start and you will just glide up it.

Defeating Ragnarok:
Before you destroy the ship that the leader tries to escape in, go to the back and 
destroy the bridge and tunnel. If you do not do this, a lot of reinforcements will 
come through the tunnel after you destroy the ship. To kill Ragnarok easily, shoot 
him until he gets by a barrel that explodes, then destroy the barrel. It weakens 
him a lot.

When you to the part where you have to face Ragnarok, before you shoot the 
ship, go on top of the small room to the right of the door. While you are up there, 
start shooting the ship until he starts talking. When Ragnarok comes out, stay up 
there. He will turn around and the doors will close with him inside. While he is 
inside, keep shooting missiles until he dies. He cannot get out. You must use a 
Mech with the Charge Up missile. Any other will not penetrate the door. 

The best Mech To use is an Atlas. Walk into the part of the base where you are 
going to destroy the dropship. Destroy the dropship and the WOB leader will 
appear and speak before shooting at you. Walk around the ship until you see a 
door where the reinforcements are coming in. Destroy the reinforcements and the 
tunnel, then walk across the bridge. Stand in the small area to the right of the 
tunnel as you are walking to it. Wait for the Ragnarok to step on the bridge. Blow 
up the bridge to take him down in health to the point where a couple shots from 
your best gun will kill him.

One at a time fighting in Grinder: 
Go to multi-player mode, Grinder, and select River city. Fight normally until two 
enemies appear at a time (one that jumps down and another that walks through 
the gate on the north side of the city). When this happens, stand directly in front of 
the gate and fight the Mech inside for a few seconds without letting it through. If 
done correctly, the Mech will get stuck behind the gate wall, and only the enemies 
that drop down will have to be fought. 100 kills can easily be accumulated this 
way. Note: This can only be done when the enemies are an Uziel or Vulture. 

Size Matters 1: Easy completion: 
Go forward from the beginning of the level then fly over the gate. Instead of going 
into the middle of that section and triggering the three Mechs, go up to the Mech 
depot. Jump jet just slightly, then fire at the missile turret behind it. Drop down 
fast, or you may be hit with the missiles. Do this three or four times and it should 
explode. After that, jump jet on top of the warehouse type of building on the right. 
Move around a bit on top of the warehouse and the three Mechs will appear. Wait 
until at least one of the Mechs walks inside the building and blow it up. The Mechs 
usually get crushed, or simply die from the explosion of the others. If they did not 
all die, repeat the trick on the warehouse next to the first one. If you could not do 
the trick correctly using both warehouses, try luring the Mechs next to the pumping 
machines then shoot them so they explode on the Mechs. There is also a second 
one that can be used in the same manner. Note: It helps to get health hidden in 
the odd, metal, twisted, dumps. Blow them up, then take the health. Also, when 
you are on top of the warehouses, make sure that when it blows up that you do 
not get caught on top; you will also be killed. Avoid this by watching the building's 
status. When it is still sturdy, every shot you make will make a flaming hole. When 
it is almost ready to collapse, it will make an opening that is just a hole or no hole 
at all. When you see that is it is almost destroyed, use jump jets then fire at it. 
Repeat that until it collapses. Power Armor will sometimes annoy you by jump 
jetting over the mountain that separates the two sections and firing at you. Ignore 
it or wait for it to jump jet and hit it with some missiles. Note: There are two of 
them; so this may take awhile. Only use missiles to destroy the buildings. 

Wolf In Sheep's Clothing: Atlases: 
If you do not care for the Atlas' upgrades, do this instead of the trick that involves 
jumping over the wall. Act normally until the Mechs turn against you. When they 
do, take out the power generator as usual. Then, run outside of the gate. Turn 
around and destroy the building to the right of the door. The doors will close, and 
the Atlases will be stuck inside. The Ullers will fly over the gate, but you can deal 
with them easily with the machine guns. After killing the Ullers, destroy all enemies 
in the area. You can then go through the level as normal, stopping whenever 
desired. From that point on in the level, destroy all units you encounter. At the end 
of the level when you are told to cross the bridges and then blow them up, wait 
until the Atlas walks on them to do so. Note: Make sure that you are on the other 
side before you blow up the bridges or you will have trouble reaching the end of 
the level. 

You will see two Atlases before the base. Go into the base and the Atlases will not 
attack you yet. Go to the satellites, then go to the door. The door will not open. 
Wait until the timer ends and the door will open and close. The Atlases will be 
locked out. 

Ready to Rok! 2: Easy completion: 
First, destroy all the helicopters, missile turrets, and tanks. Then, get the salvage. 
Next, go inside. There are two Atlases, one Thor, and two Madcats that will meet 
you. They are very difficult to fight. Once you destroy them, do not mind the little 
power armor. Keep firing Lava Gun Missiles. You will then be instructed to go into 
the middle and self-destruct, completing the level.
