Upcoming game "Warhammer 40,000: Eternal Crusade" or just "Warhammer 40k" has just released its first gameplay footage. The footage, which you can watch here, and here, and here, highlights the games MMO style. 

Behavior Interactive, who are making the game found themselves in a strange position of being committed to openness, but not having a product finished enough to show off. Obviously, this gameplay footage is still in the preliminary stages of design. 

Brent Ellison and his fellow developers Miguel Caron and David Ghozland said their motto is "Be true, be fair, be transparent." The studio has sought fan feedback from the very early days of preproduction, showing gameplay prototypes that in no way represented the quality of what the final product should represent.

Another strange element of "Warhammer 40k" is that they will start selling pre-orders before the game is even close to being finished, let alone ready to ship.  On June 25, you will be able to purchase your way into the "Warhammer 40k Eternal Crusade" founder's program, which not only nets you a copy of the full game when it's released, but also earns you access to various game modules as they are developed. The most expensive package, selling at $120, earns you access to all four of the game's factions, plus founders points, which you can use to purchase other items in the game.

Gamespot reports, " A typical gameplay session in this player-versus-player-focused game starts in your strike cruiser, where you can socialize with others and decide where on the planet of Arkhona you will land. You are taken to the surface and dropped into a predator tank, and you and your teammates might explore a nearby cavern for an ancient relic. Inside will be a swarm of Tyranids, but those giant AI-controlled space bugs won't be able to stop you. You shoot and slash your way through from a third-person perspective and collect the relic, which you then turn into high command for rewards that impact your performance on the battlefield.

'Warhammer 40,000: Eternal Crusade' is primarily a player-versus-player game, however, so don't count on the bulk of your battles being against Tyranids. After grabbing the relic, you might notice a battle raging over a nearby fortress. So you return to the predator and head to the front lines. You sneak in using cover to avoid enemy fire (no word on whether the game will have an actual cover system), and then rush through a doorway blasted open by a LanCannon. You murder your foes and find your way to the top of the fortress. Raise your flag, Space Marine: You are victorious! "

Space Marines aren't the only playable faction in Eternal Crusade; Orks, Eldar, and Chaos Space Marines will also be playable. Regardless of your faction, the game is primarily about massive online action; the battles will depict 1,000 actual players onscreen at once. Those thousand players will be using "Warhammer 40K" mainstay weapons like boltguns and chainsaws, along with psychic powers. Combat will be further invigorated by jumppacks, and you will be able to actively block and roll to avoid enemy attacks.

The game itself is currently scheduled to be released at the end of 2015.
