+
+BITGUN ([Steam][bitgun-steam], [Twitter][bitgun-twitter],
+[Discord][bitgun-discord]) by [@LogLogGames][bitgun-twitter] is an action
+roguelike zombie shooter with lots of blood. The game is built using Godot
+and Rust (via [godot-rust][bitgun-godot-rust]).
+
+They recently implemented a mission system, where you can select one of
+[three types of missions][bitgun-missions] to go to from the central camp.
+One is to defend supplies from horde of zombies, second is to search
+a facility for some object or clear all the zombies and the last one
+is to fight your way through a tunnel full of spiders and other enemies!
+They also worked on a [tutorial][bitgun-tutorial].
