The Left 4 Dead spiritual successor Back 4 Blood may have been delayed recently until October 2021, but that doesn't mean the studio has gone quiet! This latest official trailer showcases the game's rogue-lite card system.

Basically, the game's AI (known as the 'Game Director') will play a selection of cards every time you jump into a game, which can change the way the level plays out. Your team then gets to play your own set of cards as well, providing buffs to things like damage and healing, allowing you to support each other along the way.

It looks really cool and the gameplay is looking as fierce and enjoyable as ever. You can check out the full trailer courtesy of IGN above, and Back 4 Blood is currently available to pre-order on the Microsoft Store.

Looking forward to the release of Back 4 Blood later this year? Let us know in the comments.
