Wow...this game is somethin' else. I rented this NES version of Predator multiple times to finally lay low the alien hunter that had killed my fellow mercenaries...I was found wanting in that task...I could never finish the game. I became stuck in the level where you had to take a mud bath and fire your flame arrow at the Predator.
I know there is a level warp cheat code but I always felt that path lead to darkness as a gamer. Still if you have an emulator and feel up to punching soldiers, scoripions, and a few more scorpions...actually even if you do have the ROM for an emulator, don't play this game.
