ShadowDraft and me have put some good effort in the co-op ILs. Most of the maps are optimal to do with 2 players, since more bodies doesn't speed things up, just requires more suiciding, etc.

But there's at least one map that we really need 4 players to get a perfect run. That's SynTek Residential, of course. It's also the single most difficult map, so many parasites, so few ways to control them. Everyone needs to succeed at their job or the run's over.

We've been looking for 2 more players that are up to the challenge for quite a while. So if you're up for it, feel free to leave a note here!

1. Co-op up to 4 players The most fun to be had with the game is during four player co-op play. The unlockables and upgrades also keep the player wanting to come back and play just a bit more with their friends. The co-op is available as local and online.
