First level of a 5-level scenario, Krylark the Fallen. Interesting plot, but the AI can't spell worth a damn. The level is almost too difficult to bother with... lots of tight corridors filled with purple compys and tanks (nowhere to dodge projectiles, or explosions). Nice construction, though... the transparent walls in front of lava might be overdone, but there are some nice tricks. Also comes with a copy of Carnage Island (looks like version 3, but I can't be sure).
