Fully charged in sniper mode
Enter sniper mode, then hold [Fire] to charge. Once fully charged, exit sniper mode while holding [Fire]. The next time you want to go into sniper mode, hold [Fire] as you change to that view. You will now have a fully charged weapon the moment you change into sniper mode.

Using missiles on the fly
Most of the time using the battloid mode is useful for counter-missile efforts. However, with some practice you can learn to switch to jet or guardian (works either way), immediately fire a volley of missiles, then switch back to battleoid. This allows you to launch a strong assault while keeping missiles off your back.

Knifes Edge
To complete this level easy, get directly under Sckarred's feet and keep shooting.

Glitch: Floating Veritech
In the Train Depot versus level, have one player stand on one of the smoke columns. Then, have the other player shoot it out from under them in sniper mode. The column will collapse, and the player standing on it will float in midair. Do not shoot the player on top.
