I was really impressed by it. I think the health kit is perfect. It gives your players options and increases strategy. Do i spend a slot on a health kit, do I spend a slot on a med kit to heal others, do I keep pressing the action or do I back off to heal myself, do I keep shooting or do I go heal/revive my teammate. It adds a whole new dimension of decision making to the game that most other FPS lack because health automatically regenerates after a few seconds.
I also really like the item slots and costs structure a lot more for equipping your character than what other games use. I kinda hope they limit the number of skill points you can get so characters cant ultimately unlock everything and they have to decide what kind of soldier they will be rather than being everything. But then again that might not be such a good idea, because most gamers tend to want to be completest and want everything.
I also like that you have to choose a faction and you only fight for that team. I'm sure the final game you can have multiple characters but I like playing for a side rather than just random people.
In all if you just like running around killing people and not using your brain much then this game is probably not for you(i.e. my brother "I just like pwning people"). If you like strategizing and working with teammates and the feel of being part of an epic struggle then this is the best FPS and that's just based off the beta. I also think it will become the best online FPS community around once it's been out.
