Visually very appealing. As far as I can tell, the pistons are for show only (there's no reason to risk getting on them...). Nice little secret alcoves.

If these maps remind you of the Suicide series, it's because the creator of that series got the three Demolition collections started. All three of these collections have 10 maps in them. Most in this set are modified M1 Bungie maps (very much in the spirit of the first few Suicide maps, only with better texture alignment. Great flow, more weapons and ammo than you can ever use, no aliens. Very nice.

The third of 3 nepacks (10 levels each). This one's mostly original. Inspired by the Suicide series, these maps have the same play feeling, but more attention has been paid to details. Very nice maps.

2 Levels. Pretty well-done maps... One is a very nice rendition of Mike Neylon's "The Pit". (Doesn't look anything like the original, but that's what the readme says...) The other map is a model of the creator's house.
