Warhammer 40,000: Chaos Gate (Classic)
SteamOriginally released in 1998, Warhammer 40,000: Chaos Gate is a squad-based strategy game where you lead Ultramarines squads into battle against the forces of Chaos. The game is fondly remembered for its tactical depth and challenging yet fair gameplay. This is the first time the game is available on Steam, with adjustments to support modern systems (see "WHAT’S INSIDE THIS RELEASE" in the section below).

Let your dark soul feel the light of the Emperor!
Command a squad of up to 20 Space Marine warriors and pursue the evil Chaos horde through the Warhammer 40,000 universe. Chaos Gate is a squad-level, turn-based tactical action that pits you against Chaos Lord Zymran, in an attempt to unravel the mystery of an ancient relic.
Your command of the Ultramarine force begins with a choice: pursue the game plot immediately, or take on any number of random missions to gain experience and power for your squad. Whichever you choose, prepare for the unexpected - and tactical combat that’s utterly out of this world!

New widescreen combat resolutions 1280x720 and 1920x1080 have been added, complete with proper 16:9 HUD support. Music has been adjusted for improved audio balance, Steam achievements have been implemented, and the Scenario Editor has received the same stability updates as the main game.
