From publisher blurb:
Watch the skies!
vs. MARS is a small roleplaying game set during the early days of an alien invasion in a sleepy little town. You’ll need 2-6 players, a standard deck of playing cards for each player, some pencils, paper, and about three hours.
Lights float in the forest outside town. Cattle mutilations are on the rise. The military base is on lockdown. Dogs bark at something in the darkness.
Can you keep your family and friends safe when neighbors turn into strangers?
vs. MARS is a complete game, suitable for a single game session or for an extended campaign. Inside, you’ll find:
Rules for quickly creating a survivor of an alien invasion.
A fast-playing game system based on Philip J. Reed’s vs. Monsters.
A wealth of locations for the aliens to threaten.
Also in this package: vs. ALIEN OVERLORDS, a more gung-ho "take back the planet" game. It's no longer an invasion: it's war. vs. ALIEN OVERLORDS puts you in the aftermath of the invasion They've won -- or are very close to victory. Can you stop them?
