It's fantastic for someone that wants an fps 'Real-Time' action mmo, in a futurisitc Sci-Fi setting, but -without- all the 'circus' theatrics you see so much of nowadays (flashing lights, girls dressed like ♥♥♥♥♥♥♥♥♥♥s, ridiculous noises etc)
Only 'drawback' is actually related to the above, the game can be somewhat mellow so if you're looking for a massive adrenaline rush you might find this too 'quiet'.
I consider this a unique game that fits a unique role, there's absolutely nothing to not like about it other than it doesn't scream for your attention.
It's recommended to have a big viewing screen for this game, I played it on a wall (projector) 12 feet across 10 feet high - absolutely amazing (especially if you take the UI off), but played it on a monitor it's kinda hard to see.
Don't let anyone talk bad about this game it was a near perfect production, but it, you know, doesn't have young girls wearing underwear so the game kinda went under the radar.
Perfect for those who like real time fps action but want to mellow out during the evening/night.
(please note - I played this stand-alone not connected to steam, the '35 hours' is wrong I've played this for 100s of hours)
