Ikari Warriors II: Victory Road

Paul and Vince are back to take on aliens in the future in this sequel to the arcade shooter. This time out, players have multiple primary weapons which can be switched between and powered up by collecting their icons: machine gun, flame thrower, boomerang, and sword. Each weapon has strengths/weaknesses as well as effectiveness against certain enemy types. Two secondary weapons (grenades and mines) are also available and have no ammo limit.
