Modular Combat is a role-playing shooter based in the Half-Life universe. There are over 50 modules that can be upgraded at any level, in any combination. Modules give combatants amazing abilities such as flying, teleporting, spawning minions, and shooting flechettes or energy balls.
When a player gets five or more kills, they enter a "Spree" in which they earn more experience per kill and glow red. If they get up to 25 kills, they enter a "Spree War" and the whole server is against them.
