While a lot of the games are the same in effect as in Uncharted 2 (which is great), I have the following issues with the game:
1. Hopefully there's a tutorial or better introduction to MP features. I've played the games before and am able to get used to it but unless the MP features are more user friendly you'll still get a low adoption rate for the mp portion of the game. The modes and features aren't intuitive enough for casual players.
2. It's difficult to tell where opponents are in relation to where you spawn in TDM. Whenever a player spawns (excluding teammate spawns) it's usually "Okay where am I?" followed by "Okay where is the enemy?". That second question is currently a big problem.
It's clearly a very fast-paced run and gun game but it's also difficult to determine if you're running into them or from them. A lot of the vanilla Uncharted 2 maps have branching paths between player camps, so this meant that even if you had alternating spawns, you could essentially narrow down where the enemy was (which invariably led to grenade spam in Uncharted 2), with the later maps that added more upwards movement, and for which all 3 Uncharted 3 beta maps seem to be, the map is more labyrinthine.
3. I can't tell if there's an icon that reflects teammate elevation. The levels are very vertical and busy so when you're trying to link up or protect teammates, it again adds an element of searching for them that's unneeded, especially when a power-play lasts seconds.
4. Matchmaking doesn't match so well. It might have something to do with party play, but I don't see how a team of less than rank 10 could really be matched all that well with a team in their late 30's and early 40's.
There's a few technical issues too but I need to re-review some vids to make sure they're there and not lag or something I thought I saw.
