10 Chambers Collective’s first person co-op horror game GTFO released for PC in early access late last year, and has been going strong since then with regular updates- or “Rundowns,” as the game calls them. Its third Rundown, called The Vessel, is set to launch imminently as another free update for all players, and the developers showed off a lengthy gameplay trailer to get a taste of what it will bring at the IGN Expo.

The trailer shows plenty of slick co-op action against oncoming hordes of monsters, showing plenty of combat footage of a group of players going through a creepy looking (to say the least) lab. Those who’ve been looking forward to this Rundown will want to take a look at this footage- you can check it out below.

GTFO has been available on PC in early access since December. A full release date for the game hasn’t yet been announced.

We haven’t heard too much about GTFO, the upcoming co-op shooter from 10 Chambers Collective with an emphasis on horror. However, over the past few weeks, new gameplay footage has emerged en route to the game’s Steam Early Access launch. The latest sees a team sneaking carefully through an area with a fog of war masking the map.

As a result, moving carefully around the monsters is necessary. If alerted, a whole mess of enemies could suddenly begin pouring in, which is bad seeing as how resources like ammo can be limited. Players can mark different areas and you can see the team’s status at all times.

Overall, GTFO is looking to differ greatly from your average, Left4Dead-style horde shooter. Currently slated for PC, you can sign up for the upcoming alpha by heading here. The alpha starts tomorrow and ends on November 3rd. Stay tuned for more information on the early access release date in the coming days.
