Unlockable: Characters and Bonus Arenas

Unlock the following by earning the appropriate number of multi player points, earned by completing objectives in co-op mode.

Unlockable: Arena Mode

Play through the cooperative missions and acquire multiplayer points by completing the optional objectives.

Battling flood

Using a combination of assault, Shotgun, and grenades works best. Warning: Only use the (sticky) grenades at a far distance, especially for the little ones.

Eliminating enemies quickly

While you are facing a lot of enemies, press [L] to aim and shoot with [R]. Continue to press [L] and you will go from enemy to enemy, weakening each without eliminating one by one. You can also do that and dodge shots if they get a chance to shoot you by pressing [B].

Dart Gun

When you get the Dart Gun from Q, he says it will knock out your enemies for a few hours. However, it will actually kill them in one hit, just like the Golden Gun. Note that it does not have a long range. Save the gun until you are low on health or are surrounded; it is very useful.
