GTFO devs 10 Chambers Collective has revealed a new enemy type in their latest gameplay trailer that should up the already high tension presented in the game. The Shadow enemy can only be seen when illuminated by light sources such as a flashlight. In fact, this makes it almost impossible to see from static screenshots. The skittering around is definitely not something you expect (or want) when you’re trying to barricade yourself against other monsters.

Also of note is that GTFO will be available and playable at Gamescom in Germany next month, where they’ll be showing off the game at the Unity booth. The game is still slated for release later this year, but there’s no definite release date yet.
