Relic Entertainment's Warhammer 40,000K: Dawn of War II has been tearing up the sales charts since its release in February but there's always more money to vacuum up. To give the game a boost, there's now a single-player demo and discount available for the game.

The demo allows you to sample some of the single-player campaign, which stars the Space Marines. Should the demo strike your fancy, you'll be able to buy it through Steam for 25% off, making it $37.49 instead of $49.99. The offer lasts until Monday, April 20th.

If you already own the game, Relic's got something for you too. A couple days ago they released Patch 1.21, complete with a new multiplayer map and a number of gameplay tweaks and fixes.
