Back 4 Blood dropped last October, but the game is back in the public eye due to the substantial first expansion. Fans of Left 4 Dead can get their fill of first-person zombie action in the spiritual successor to the long-silent series.The game has many elements of a roguelike, which ensures that progress is incremental, and every game over forces the player to restart the run. While there's a critical path that players must make it through to beat the game, there's far more content beyond those bounds.How long is Back 4 BloodBack 4 Blood's central progression features 32 levels, split into four acts which must be completed over a run. While the new Tunnels of Terror expansion has added new PVE environments, most of the central content is present in the main game.Back 4 Blood@back4bloodIf hugs aren't your thing, stay away from this guy.2:00 AM · Apr 15, 202256555If hugs aren't your thing, stay away from this guy. https://t.co/RqXQ52GB5EAccording to How Long To Beat, the best resource for video game runtimes, Back 4 Blood's main story takes around 11 1/2 hours to beat. A skilled and speedy player can put down the main story content in just 8 hours. The speedrun world record comes in at a brisk 30 minutes and 54 seconds, but most should expect between nine and twelve hours.Adding on the side content, including secret hunting or strange back alleys, players should expect something closer to 18 hours. The high teens to low twenties would be the average guess for a more inclusive run.Taking on the 100% run is a sharp increase in time investment. Players will need to make several runs to unlock everything while also gaining the benefit of the RNG. Completionist runs can take over 100 hours, but suggestions as low as 52 1/2 hours have been listed.Back 4 Blood's length in contextBack 4 Blood@back4bloodTunnels of Terror are about to emerge - read more about how to better equip yourself and what to expect in the patch notes below! back4blood.com/patch-notes/ap…12:00 PM · Apr 12, 2022924145Tunnels of Terror are about to emerge - read more about how to better equip yourself and what to expect in the patch notes below! back4blood.com/patch-notes/ap… https://t.co/VMZMoY9yzRComparing the game to Left 4 Dead is tricky, but it's the fairest comparison point.
