A truly glorious two-player board game, the premise of which being that the good ship Znutar, under the command of doughty Captain Yid (one player), has become infested with the afore-mentioned awful green things (the other player). The crew must combat the AGTFOS, either through brute force (unlikely, as the AGT reproduce at an alarming rate), or by trying out various weapons and supplies (my favorite is zgwortz) to see what has the more deadly (or reproductive!) effect (the effects are randomly determined at setup time, and the Znutar player only finds out what does what by trying things out). Antics ensue.
