Maps with large numbers of spawn points.

I am lookinb for maps with large numbers of spawn points, preferably with a good density,

I found the troll tunnels so far, and they are great. But I have looked through many office, warehouse, and outdoor maps and most of them don't have that many spawns or the spawns are spread out too much.

Any suggestions?

From what I've seen, tunnel or underground maps in general seem to be your best bet. Offices and outdoor maps by their very nature will have a lot of "featureless dead space".

I've used some 'CoT small' maps in a recent mission of mine (as well as some different caves in another), and on a large team (or with the proper team-size settings) the groups of foes often seem to just about bleed over into one another (agro fun!) when enough of them are spawning.
