Battalion Wars 2 Cheats :
Invincible Frigates - Anglo Isles - Up Periscope
by Unregistered Oct 05, 2011
Another way to cheat in 'Up Periscope! This time, when Admiral A-Quira sends submarines, control a frigate, and 'run over' the submarines. Aim at them and fire depth charges (underneath you.) You will be invincible to all submarine fire until you run out of ammo and need to refill.
