Biocube is an amazing map I enjoyed on my other server. It's on the smaller size but there is a lot of areas to snipe from. It's pretty fun and I don't think it would be too laggy. Let me know what you think . Spoiler: Bio Images https://garrysmods.org/download/2332/ttt-biocubezip
Lots! Its a small map but there are buildings and rooms and walls plentiful enough for a chaotic match. My old server didn't have c4 but i can imagine this being better for c4 then clue. Only because they wouldn't all be so close together.
Over maps like Kitchen, Bank, Highrise, and other horrible maps on the server this is so much better.
Map is fun, even on the 'laggy' side of things. It could be worse. I say worse because Frozen is an example of FPS hell. Anyhow, the only problem I see with the map is the traitor room. While it would rarely be used by traitors, I can see innocents getting stuck in there via a few means. One being a teleporter that they decide to mark in there, or traitors letting them in there only to be stuck for the rest of the round as C4 is planted on the outside to screw them over. +0.75, otherwise.
