Be sure to get Crymod Launcher first to make playing custom maps much easier
Strange Island
The title sums up the map pretty well. It's heavily scripted and just plain odd in some areas.
look at the youtube video of it to get an idea. Especially watch from 5:45 to 6:02. Yes that guy is sitting on a toilet
Crashed
Open ended and well designed. Worth a playthrough.
Physis III
Hilarious map. Look at the screenshots to see what this map is like.
Frozen Island
This is what the final levels of Crysis should have been like. Several paths through the jungle.
Savanna2Jungle
Still have to try this one out. Screenshots look nice though.
