Picture this: You’re rolling down the L.A. river in your armored MarkVII TT tank. You feel pretty confident that your main 110mm SledgeHammer cannon can take on just about any threat that comes your way. Your only concern is ammunition. But lo! you spot a crate of high-velocity rounds you can pick up just ahead. Enemies are all around, but you bear down on your target and go straight for the resupply.
