Rush'n Assault

Rush'N Assault is a clone of the arcade game Ikari Warriors. In it, you play an army commando, and have to raid an enemy stronghold using both guns and grenades (which you can launch over walls that protect your enemies from normal gunfire). You have limited quantities of each, so you have to pick more of them up as you play. A fun part of the game is that the two player mode has you both playing at the same time, so you form a team to raid the enemy fortress. The game does actually end when you make it the final fortress and rescue the Prisoners of War (POW's), and receive 50,000 bonus points.
