Set in the grim distant future, Warhammer 40K: Chaos Gate - Daemonhunters by Complex Games requires you to take command of a group of Grey Knights - elite warriors trying to stop a Chaos God's plague; fighting the daemonic servants in tactical turn-based combat.
Well, the title basically says all you need to know (if not, wait until the end of the Introduction). So, what are you waiting for? The armies are gathered. The grim champions of ruin await your orders. The banners of Chaos fly upon the dark walls of the citadels, and the trumpets call your warriors to battle. There's no time to waste. Strike before your opponents have gathered their strength. This shall be your moment of triumph.
In the grim darkness of the far future there is only fantastic gameplay. In Warhammer 40,000: Mechanicus your objective is to purge the Necron presence on planet Silva Tenebris. You play as Magos Dominus Faustinius, leader of an Adeptus Mechanicus ship and the troops on it.
