-Free to play.
-Tactical Gameplay that encourages teamwork.
You need to pick up your teammates when they downed, and tie down your enemies.
-Good variety of maps. 6v6 or 12v12 quick games.
-Good built in push-to-talk voice communication (not always on).
-Very minimally buggy, very smooth beta with minimal hangups.
-Spotting function by pressing 'Q'.
-Basic variety of starting weapons that feel pretty good: Assault Rifle, SAW, Shotgun, Sniper
-Different sight attachments to choose from.
-You can have two sets of grenades at a time, 4 different types to pick from:
1 HE, 2 Stun(Flash) (Up to 4), 2 Smoke(Slow) (Up to 4), 2 Fog(Fast) (Up to 4).
-Newbs don't really pick up, tie down or spot. It might just not occur to them, but reminding them or reviving them yourself usually helps them learn.
-Only 1 kind of pistol currently.
-No female soldier models. Can't pick which male model you use either.
-Bug: Sometimes the guns hangup and don't reload/shoot. Could be lag though.
-Bug: Poor steam integration. Doesn't properly report server player count and doesn't always let you join directly through steam. You may have to ask a friend for an invite, or look up the server info and type it directly in AA's IP box to connect.
