"Warhammer 40K: Storm of Vengeance" is the latest Games Workshop title, currently in development at Eutechnyx and it's due to launch March 27.

"Warhammer 40K: Storm of Vengeance" sees the Dark Angels marine faction fighting Orks in a five-lane tower defense games across a 50-level campaign based on the book 'Purging of Kadillus' by Gav Thorpe.

Both sides have their own resources, unit types and crafting trees. The Dark Angels can use a resource called Redemption to buy unit cards from production structures such as the Rhino tank. There's also a levelling system that can be used to upgrade units and another resource type called Resolve that is used to upgrade hero units.

Players place structures into the play-space, and the winner is whichever side destroys three of their opponent's buildings first.

In single-player, clicking or tapping on a building pauses the action. Outside of single-player there's cross-platform multiplayer, which enables PC, iOS and Android players to play against each other. This is faster paced, as clicking or tapping on a building does not pause the action. Multiplayer battles affect your multiplayer rank and feed into a Risk-style faction war. Every 14 days players earn campaign medals based on how their faction is doing in the wider war.

As mentioned the game includes the Space Marines and the Orks, but Eutechnyx will sell a third faction, the Imperial Guard, on launch day as 69p DLC. They intend to add other factions to the game some time after launch.

On Steam, "Warhammer 40K: Storm of Vengeance" costs £6.99 while on iOS and Android it costs £2.99. Eutechnyx confirmed that the game will not have micro-transactions.
