A sprawling, symmetrical, multilevel map which is extremely easy to get lost in (since it looks the same in many places). Dark, and big, and hard to figure out if your fodder is above or below you... this one is good for lurkers.

My first netpack. Rather simplistic design in some levels, but still fun to play. Has 35 levels which support all types of play. Good for 2-8 players. Works in both M2 and Infinity.

5 levels, sort of a wide range. Some seem to be designed for solo practice (too many aliens for a reasonable net game), while others seem to be designed for net play.

A tiny (well, sort of) 5D map with 3 distinct, spatially overlapping areas. Once you've gotten the textures down, it gets a bit less confusing... but it's all small enough that Jinx_tigr's favorite bug (damage in one frame of reference affects those in another) is abundant here. As Pushkin says, "i'd rather be hit over the head with 5d space anyway." Play it! You'll have fun.
