Stays pretty close in feel to the original. One major difference, though... getting that spanker is a bit more painful than it used to be. (Seems like there are more purple compilers than in the original, too... those circling green bolts in the carnage pit are a pretty eerie sight!) Update has some tweaks (better lighting, some sounds, movement to the lava).

A pair of small arenas. Nice flow, and no aliens (although the Bobs in Chess can be a hassle). The readme only covers the first map... Nice placement for the alien weapon on The Abyss. (You'll stumble on it...)

A small arena, and a large ammo room... most of the ammo is suspended (get good at elevators, or die), and watch the lava traps! A few neat tricks...

ThunderDome with an attitude (and a nice launching start...)
