Complete the following achievement to get the allotted points.

Fight your way up to the building to the left from your beginning viewpoint. When at the back of the building with the stairs, go to the top or just stay on the ground, You should see a large wall with a nice designed bar gate. Press Y while aiming in the middle area where there is snow. Once at the top on this ledge aim at the tip of the gate. Make your way over the gate to skip the fight with the large mech below the right building.

If you are taking heavy fire and would like to replenish your health (if you have the thermal energy) hop into the nearest VS. While it is doing the startup animation, you will be invincible for about five seconds.

If you have alot of Akrid or other things after you while riding the sled VS press LB to do a boost jump. While riding around you can also jump snow piles and get air.

When you face off against the snake like creatures go to the left as far as you can and move along the edge. The snake wont attack but will circle you. When you get to the end quickly move to the shelter after getting more energy and face off against the boss.

Use the following in multi-player mode to perform the corresponding taunt or command.

Hold Start and press Up: Say "Let's go".
Hold Start and press Right: Say Oh yeah".
Hold Start and press Left: Butt slap and bow.
Hold Start and press Down: Gun in the air.

When online you can taunt people by pressing Start and the D-pad. Three of the taunts are the same for all the characters in almost the same way. However the fourth taunt is different.

Basic character #1 (pointed ears): Humping
Basic character #2 (big helmet): Bow
Basic character #3: Butt slap
Stranger: Holds out his arm
Soldier: Claps
NEVEC: Stands straight as if in the army
Yuri: Kneels as if praying

Hold LB or RB to charge it up. When you get close to whatever you want to hit, just release it for a hit. This is easier than pressing it at the spur of the moment, because it sometimes misses.

The useful anchor that everyone uses to reach high places can be used a little further if you press A + X instead of just X. Keep in mind that this only results in a slightly further distance.

In order to do this trick you must have a VS with two empty arms as well as two Gatlin guns. Attach both guns to each side of the VS and fire only one of the guns a few times. Then, start firing the second gun. If done correctly, one of the guns will reload while the other is firing and repeat, causing the guns to never stop firing until you run out of bullets or manually reload. This works well against any Akrid Boss, especially the one in Mission 05.

Take the rifle that you find at the beginning of the level. Snipe the head of the rider of the VS. It will take about two or three shots but he always goes back to the same position for an easy snipe. Disregard all of the other people shooting at you. Run and get into the VS. Kill your way to the end of the map. Then, get out of the VS and go through the door. Once in the next part of the level, run to the VS which is on the ground forward and slightly to the right of you. Destroy the other VS that are trying to destroy you. Note: The Boss VS is the VS jumping around.
