Hello, it's been a while but here's an update:

Patch notes:

New content:

• New level editor for making your own maps to play in custom battle with 5 demo maps I have pre-made
• Lots of new objects to use for the level editor, I also added a few new variants of bases for the generated maps
• Sliding while sprinting (press the crouch key)
  
• Parachutes when falling, also implemented fall damage if you don't use it
• New guns (SMG and a revolver)

Improvements:

• Textures and animations on existing guns
• Graphics features (lighting options, FSR2.1 option and improved colour grading)
• A pass on the UI to make it more consistent
• Audio improvements (gun sounds and music)
• Misc bug fixes
• AI behaviour (fps mode)
  
  The game is now 1.5gb download so I've had to use google drive to host it.
  
  Future updates for itch version will likely focus on fixes, controller support and then the full release with Steam including a campaign, a new faction and hopefully Steam workshop for the level editor (all of this is subject to change of course but that's the current plan).
