Call of Duty: Modern Warfare 3 (2011)

This is the game GRN is built on. Seven servers across multiplayer and survival, running on Plutonium IW5 - a client that keeps the 2011 game playable long after the official servers went quiet.

Multiplayer runs a rotation of stock and custom maps with bots filling out quiet hours, so a server is never empty when you join. Survival runs co-op waves with a shop, a bank, and records tracked per map.

Every kill, match and survival run on our servers is recorded and shows up on the leaderboards here. Link your account and your in-game name maps to a profile automatically.
