Amazingly fun game, has co-op too, but you can have as much fun in a single player too.
Played Insect Armageddon, 4.1, 5 and Iron Rain, and definitely looking up for worldwide release of 6.
You should definitely try it out, just look up HL streams for it if you're not scared of spoiling yourself a little bit.
