Arma 3 is ready to launch into its first public alpha test on Steam, and anyone who pre-orders will be given access to this early look at the game. There isn't going to be a lot of content included, but there will be four missions that try and show off different aspects of the military shooter ranging from scuba diving to infantry and vehicle combat.
If you haven't pre-orderd Arma 3 yet, don't worry -- you'll still be able to check out a free invite-only "lite" version when it arrives a week after the full alpha that's landing on March 5, 2013. However, similar to the current free version of Arma 2, you won't be able to play multiplayer or use mods.
Bohemia Interactive is hoping to be into beta by summer with the full game release coming in the fall. I wonder how long it will be before someone makes a zombie mod?
