Space Hulk

Possibly /tg/s favorite board game, rivaled by a select few such as HeroQuest and Settlers of Catan (which is Mornington Crescent gay).

Features two small factions from the 40K universe: Genestealers, a subspecies of Tyranid who tend to infest Space Hulks so they can OM NOM NOM Space Marine Terminators who enter these hulks to recover long lost technology and pretty much kill everything they see. The game is fuckhard for both sides - Genestealers, because they have no ranged weapons, and Terminators, because they have little mobility, few numbers, and, for all but a select few Terminators, are very vulnerable in close-range combat. (The deficiencies in hand-to-hand can be made up by equipping Terminators with Lightning Claws or the Thunder Hammer and Storm Shield, both added in the Deathwing Expansion.)
