Well after playing for a few hours, here are my thoughts:
(I'll compare this to other
free FPS games.)
Positives:
Free. Of course a positive thought

Weapons. There are a good amount of weapons in each class, and you can buy any gun you want from the begining as long as you have the money.
ADS. You can aim down sights, which lacks in most free games. It's accurate and works like any other paid FPS.
Decent Graphics and Sound. Compared to other free games this game probably has one of the top graphics.
Good animations. Seems they are stolen from BFBC2, but who cares?
Negative:
Browser based launcher. I hate those.
No prone?
No video settings available except for Resolution, Fullscreen, and High/Med/Low graphics.
No server list.
Bad matchmaking
No in-game class change. Once you select a class, you stick with it, no changing it until you create a new soldier and start over.
Weapons "bought" in game don't stay forever.
Too many vehicles. 16? Dayum.
Fixed Spawn Points. Essentially you can camp spawns and people will spawn in front of your face.
Slow movement. Even slower than BFBC2... This makes slow and campy gameplay :/
This is still BETA, so some things like video settings and spawn points might be fixed later on. But I don;t think I'll be playing1 this game any longer since I have BFBC2.
