GoreBox is a first person sandbox developed by F²Games, an indie developer team, focusing on brutality and gore. With a variety of weapons, there are many ways to kill the GoreDolls, your creations. A widespread virus, created by you, turns humanity into brainless "dolls". You are equipped with your Reality Crusher V2, a kind of "tool gun" that can spawn, delete, drag, and do much more.
Join the F²Games Discord server listed in-game, or join it here. Many updates on the game are listen in the server that are not uploaded onto TapTap or the Play Store. It also has a thriving community with over 100 thousand members. (Disclaimer, they can be a bit weird or silly.)
Overall, I give the game 5 stars and I couldn't recommend it enough. Play it. Now.
