The modder that created the ARMA2 mod Battle Royal has gone on to make his own standalone game based on the same concept.
It's built using the Unreal engine and is extremely addictive. It's all the fun stuff from the mod or DayZ or H1Z1 without all the crafting and base building bits.
For those that haven't played a battleground game the premise is as follows:
You're put on a plane flying over a 8X8km tract of land with diverse landmarks and cities. You only have the clothes on your back. Once you parachute in you have to scramble to find weapons, armor, vehicles and fight off the other 95 players to make it to the end. All while this is happening there is a collapsing energy fence that you have to stay on the inside otherwise you start taking continual damage which forces people inward and toward an inevitable conclusion.
It's very random and very intense as well as being extremely addictive. If you die you queue back up and at it again for another try within seconds.
You can queue up as a team of 2 or as a lone gunman. The duo mode allows for a knockout mechanic and you're able to revive your teammate if they're not taken all the way out. They're talking about a mode that allows teams of 5.
The pre-Orders have already sold out, but the game goes early access next week on Steam. I'm definitely going to jump in on this one. Gunplay is solid. The mechanics are solid and it's very quick shots of adrenaline.
I was lucky enough to get a beta invite from Jakeleg and for the most part we kept getting in the #20 mark, but did manage to make it to the end (well Jakeleg did. I had an altercation with a car near the end) once.
