Since all the 6 hour maps outside of Right2Live have been posted in this thread I'll do them all here:
Peanut's Speed Mine: Surprisingly solid for a six hour map, falling down at the start was kind of cheap though, especially as the energy loss varies somewhat (first time I was down to about 65, then the next I was in the 80 range). At the end I was so low on ammo I had to rush down the "boss" with the Biorifle, but in a map this short that sort of craziness kind of fits
. The approaching Brute line of doom was also fun (these maps in general seem to be giving Brutes some time in the limelight
). The texturing fell apart a bit when you reached the lower level, but it's acceptable for its build time.
Speedfall: Lolwut. Insane, and the sequence at the very end is pretty cool.
ZuperUltraSpecNazSkaarjKillerParachuteMan: Lolwutx2. This could make a good aim training level with a HUD that listed how many hits you've made.
Right2Live: Legless Krall of doom!!! I'm not so much of a fan of completely aimless levels like this, however, the potential improvements for the compilation version sound very cool and could make it completely different.
