Navagon: I don't know, man. I don't see rubber ducky puzzles going down too well in a game that describes itself as a shooter.
GameRager: Of course I meant more "manly" item carrying/combination possibilities.
The ONE thing I've always hated is that you can have a laser or rocket launcher or some badass weapon and you need a card to open the fucking wooden door.
BLOW THE FUCKING DOOR OFF ITS HINGES FFS!
THAT is the weaksauce link in many shooters. Oh, and ammo in boxes everywhere? Money too? Seriously, that's super bulshit.
My idea:
Ammo - MUST be looted from enemies. And no, you can't just "reload" and have a full clip. You need to find cover and start loading the cartridges while they're after you. Yeah, shit-in-your-pants mode.
Money? Same thing. If you're in a city style game, well maybe shoot the kneecaps off some of the baddies and rob them, beat them until they give you their atm number. Something other than "Wow, what kind of retard puts a few dollars EVERYWHERE IN THE UNIVERSE????"
Doors? Well, unless it's the vault door from Vault 101 well, fuck yeah, if you have TNT then USE IT. Or kick the door down. Or use the butt of the gun to smash the padlock.
