Warhammer 40,000 (Tenth Edition): Ultimate Starter Set

From BoardGameGeek:

Across the far-flung worlds of the Imperium of Mankind, in a galaxy riven by warp storms and unceasing conflict, the armies of Humanity battle for survival. With the Imperium already standing upon the brink of annihilation, the Tyranid hive fleets emerge from the cold void between the stars. The Space Marines stand as the last line of defence between this ravenous alien menace and the beleaguered worlds of the Imperium. Take the plunge into the 41st Millennium with the Ultimate Starter Set for Warhammer 40,000. This box gives you a complete introductory experience, with loads of incredible models, a battlefield to fight over, helpful guides, and all the dice, tools, and rules you need to play your first games. Pick the noble Space Marines or swarming Tyranids, give control of the other army to a friend or family member, and battle it out for hours of entertainment. There's no better way to get into the Warhammer 40,000 hobby – this box is also an excellent way to expand your existing collections. -description from the publisher
