Release Date: June 11th, 2012 (Beta Build 9968.0)
In-game Hotlink: Carl
Carl was available exclusively through the PAX Prime 2012 promotion via PAX Promotional Code Cards handed out by CarbonGames from their booth at PAX conference in Seattle on August 31 to September 2, 2012. Now it's available via PAX Crate.
Carl is an Infantry-centric Pilot. If you do a lot of Outpost capturing then this Pilot is for you. Although you get 8% less in-game experience, Infantry move 5% faster and have 6% more attack and defense. Useful when you have Bot Spawners because the increase in stats affects the spawned Creeps.
