Icarus: Alien Vanguard, originally by Team TNT, has been ported to ZDoom! Fight against the hordes of invaders as you blast them away in exciting, well-designed maps ported for Skulltag, ZDoom and other advanced engines. New enemies and weapons await you. Alongside is the remixed soundtrack and emphasis on story, through intermission messages. And if you think that sounds great, there is a working currency system to purchase goods off of Icarus, the ship, from robots. No need to worry about needing that health pack now!
