The newest Warhammer is Sanctus Reach, a turn-based strategy game developed by Slitherine.
There has been a slew of Warhammer games in the works of late, and the latest looks like it might be the closest to the tabletop yet. Turn-based strategy title Warhammer 40,000: Sanctus Reach is being published by Slitherine, who was also behind another turn-based game, Warhammer 40,000: Armageddon. It's being developed by Straylight Entertainment.
Sanctus Reach puts players into the giant metal boots of the Space Wolves, one of the more popular Space Marine legions. The Orks are taking over the galaxy, and the last planet standing is Alaric Prime, where the Space Wolves hold fast.
The official line on the game reads,
"Warhammer 40,000: Sanctus Reach brings you to a dark era of carnage and endless war. There is no peace among the stars: the Imperium of Man is beset on all sides by all kinds of threats. Among them is the Orks, a barbaric and warlike xeno race. One of their fiercest leaders, Grukk Face-Rippa, leads his Red Waaagh! in the Sanctus Reach system.
Worlds after worlds fall to billions of Orks, until only one last planet resists the green tide: the Knight World of Alaric Prime. This is where a brave company of Space Wolves makes its stand to defend the last bastion of mankind in the system..."
According to the game's Steam page, it will come complete with two story-based campaigns, 30 Space Wolf units, 30 Ork units, a skirmish mode, a map generator, and multiplayer.
If you're interested, Warhammer 40,000: Sanctus Reach is set to launch in November 2016.
