Doom 4 could be three megabytes total

A first person shooter that clocks in at 96 kb. That’s right. The whole thing is 96 kilobytes — the size of most spam. The game is called .kkrieger and it’s the work of a small developer. Though the game is in beta and really only includes one level, it’s still an engineering feat. You have to see it to believe it. What this might mean for gaming in general? Not much, except a lot of jealous and intrigued programmers.
