Surprisingly Addictive!!
I went out and purchased the game, and have been playing it for several days straight. Even though it is only loosely based on ShadowRun, I can't escape the feeling, like I'm trying to power up in the 'Caryards' (for those of you who remember the original SR) but in the first person. The fact that this game was given such a poor review by the official Gamespot reviewer is kind of sad. Criticizing it's ammount of maps, seems like a shallow reason to give a game a permanent low score. I have absolutely no doubt that they will be releasing more maps, and the ones that they do have are incredibly fun.
The bottom line here is this: If you want a fun multi-player, with some Very innovated ideas and RPG elements, this is the game for you. If you hated CounterStrike - don't bother. If you loved CS give this a try.
The load times are a little long, but well worth it, and the community is really cool. Definately encourages teamwork, I highly recommend this super charged team based action FPS. I will give one cool example of an innovative feature of this game.
When you are playing the game, and see an enemy, you can say press 'up' on the 'D' pad. The game itself will have a voice that tells everyone 'elf spotted by the elevator' and then everyone will have a symbol of an eye on their screen, if they look in the direction of the elevator. The same applies for calling for backup etc.
