I've set up a Doom-inspired game jam. It is currently open and will last for almost 4 months. The idea of the jam is to submit games based of the "Doom" video game series primarily, but can also take inspiration from other shooter or combat focused games such as Blood (1997), Heretic (1994), Unreal (1998), or Quake (1996), etc. This is the overall purpose of the jam. Here is the link and I hope you join!
