Select the "Extras" option at the main menu. Then, select the "Gallery" option. Press Square(2), Triangle, Square, L1, R1 then view images 41 through 47.

If there are no more health pick-ups, and a player is on low-life, you may want to use friendly-fire to kill the player then revive him. Reviving a player restores him to their full health, and may be something to think about on the Inferno difficulty.

Perform the following actions to unlock additional guns.

Pesticide Cannon / Tier 8 Rocket Launcher - Achieve Rank 8 with the Trooper Armor.
Pesticide Missile / Tier 8 Missile Launcher - Achieve Rank 8 with the Tactical Armor.
Pesticide Mortar / Tier 8 Grenade Launcher - Achieve Rank 8 with the Battle Armor.
Pesticide Rifle / Tier 8 Sniper Rifle - Achieve Rank 8 with the Jet Armor.

When taking a weapons box (or salvage box) in an Earth Defence Force Insect Armageddon online match, all players in the match get the weapon (press TRIANGLE or Y at the end to see salvaged weapons) regardless who picks up the box. The notification of what you get just doesn't appear on your screen, that's all.
