Action Games
66Action games are about reacting faster than the game can kill you. Shooters, arena brawlers, bullet-dodgers and reflex tests live here. The browser action scene is dominated by short, intense loops — the kind of thing you load for three minutes and lose an hour to — and the open-source community has produced surprisingly polished entries that rival native downloads.
