One thing that's in the back of all our minds is that it's very Uncharted like. I'm not necessarily sure if that's a good or bad thing yet... but hey, I still enjoy parkour type games. Having an uncharted type game on the PC is pretty awesome too.
I was only able to touch 45 minutes of it last night, so I can't completely judge it at the moment. Although, I do feel like there were more things that frustrated me then the things that impressed.
So, I know the multiplayer is based off the single player's gameplay completely. But... to be honest, the gun combat really doesn't fit well in a multiplayer type setting. You always put away your gun after it holding it for 5 seconds. Sure, it's a small little annoyance... until I found out blindfiring(Hipfiring) wasn't possible. The only way to shoot is to aim... which, I guess isn't a bad thing. Still, it just feels odd and kind of makes me dizzy after a while. Having to aim at someone 3 feet away isn't fun. :L
The parkour seems to work quite nice, the lobbies aren't horrible, and the weapons feel pretty ok. (Even though there is somewhat of a lack of them. 8 Primary weapons and something like 5 or 6 secondary weapons?...) The traps are a nice touch too. It's small... but sweet. I have to say though, I find the character selection menu to be... silly. It's just a bunch of people in the middle of a swamp, frozen in time, making the craziest poses!
In conclusion, what matters most is the player's opinion. They're the ones who will keep the game alive after all. What do you guys think?
