Warhammer 40,000: Space Marine 2, in addition to being awesome, is a major hit, with publisher Focus Entertainment revealing more than 4.5 million genetically engineered super soldiers have heeded the call. That's a pretty impressive effort in just over a month and best of all; there's plenty more carnage to come, entirely for free.

In a surprisingly involved update, Focus revealed the happy news and outlined just a few of the features either enlisted or prospective Astartes can look forward to facing. A Lethal Difficulty is being added for those requiring further penance and new cooperative Operations. One will feature the colossal Hierophant Bio-Titan and a return to the swamps of Kadaku. Fans of the Dark Angels will be pleased to know that the sons of Lion El'Jonson will be next to receive their cosmetic due, and the Neo-Volkite Pistol is also being added to the Battle Barge's armoury.
