If you beat the game on easy you can buy the matilda and the infinity launcher. If you beat the game on pro. you can get the p.r.l.412 and that is the one thing you want!!! also if you get on top of the merchant shop in the lake cave you can walk out of the roof and into the wall you can get a shotgun on all versions but not ps2 re4 version... sorry. and if you beat separate ways you can get leon's gangster uniform, Ashley's knight gear (that makes her to heavy to carry away by zombies and she can jump down ladders alone !!), and the Chicago typewriter.
