Ok before I praise the uniqeness of Shadowrun I will get a couple of the minus points in first.
Ok it is for Live play only and there is no single player campaign (Don't buy if you want this) There are a few little glitches in the game i.e. non animation when someone goe's up a ladder. Sometimes connection can be a little annoying.
Now that I have got the few gripes that I have with this game, let's get to the good stuff.
First and foremost, Shadowrun is FUN!! You can play one of four races, each with it's own strengths and weaknesses. This allows for lots of different approaches to gameplay on a strategy level, if you want to play aggressively try the hulking Troll who can suck up lots of damage, or alternatively if you like to hit n run try the fast and self healing Elf. There are 2 other races that I won't go into, but they are great too. The thing that impresses me the most is how balanced the four races feel, none is truley superior than the others.
Once you complete the simple (but effective) training mode you are ready to play your first Live game, this is where the fun starts. You are matched up by the AI (supposedly) with players of similar trueskill to yourself. So when you start you should be with players of similar skill and experience as yourself.
You can now purchase weapons and a choice of Magics and/or Techs. These as well effect your approach to gameplay, a fair few differentials here on what you buy, and how you then go into combat. As you progress through the rounds you earn yourself more cash to purchase more goodies. After a couple of rounds you can wield some tasty weapons as well as magic and techs.
There are 3 different gameplays, 2 mainly involve capturing the artifact (a little like capture the flag on other games) and the other one is purely a deathmatch sort of gameplay, where the object is simply to take out the other team.
All in all Shadowrun is by no means perfect, it could do with some fine tuning, I am not sure whether this will be addressed, but if it did with Downloadable content this game could be made near perfect in my opinion. But it is a game that is unique as a FPS go's, what you will notice is that NO 2 MATCHES ARE EVER THE SAME!!
If you are unsure on Shadowrun maybe rent it out, but I believe that the majority of you will think it is money well spent.
