Well, this is a pleasant surprise. Mashed, an arcade racer released on Xbox and PS2 (and in some places PC) a decade ago, just hit Steam. This, along with Broforce, are two very good reasons to start using your PC for local co-op.
While there's a singleplayer experience to be had, the real joy with Mashed was/is in its local multiplayer, which comes closer than any other game to matching the madness found in the classic Micro Machines racing game.
Racing from a top-down perspective, it's a brutal game, but one stage in particular -- the snow/ice level -- remains my absolute favourite multiplayer arena.
