Today I hacked together a crude inventory system for Radpoison. You can pick up weapons, toss 'em away, and of course loot them from fallen NPCs. I'm considering switching the current graphical icon scheme to something text based instead. Pictures are indeed prettier, but for prototyping sake text gets a much more precise understanding of what items are than my clunky pixel work. It worked for Teleglitch, right?
EDIT: Oh, hey, the curious can totally play around with the current build right here: Radpoison-Mar_29_2015_00_21_56
