Warhawk was awesome. Especially now that many people have the game. The graphics are damn good especially in the warhawk.
The headset is damn good, I can hear others and they can hear me, but you can only talk to those on your team. I used the headset with my phone and it work perfectly and none of my friends could tell the difference in sound quality. I even did a voice chat on the ps3 to test it out, pretty cool.
I am loving the warhawks but also the ground fighting as well. I was picking people off with the missile launcher in one game and i think I pissed off a few people because in the second game they came gunning for me on the ground and that launcher isn't very good at ground targets so i had to jump out and defend myself. That part was excellent since i mined the area and took out 2 guys in a jeep with a mine and grenade. After that i went to higher ground and used the rocket launcher against some warhawks and people trying to invade my base.
The fun ended in the second game when most of my team left or switched sides so there were a ton of blue invading the base. i stayed to the end defending the base. lol.
