The Unreal BattleTank topic gave me so many ideas that I decided to make a new Battle Tank from scratch with some similarities and some changes. I called it Tank Arena Shooter and I just finished the Split-Screen version of it, where 2 players can battle each other in 1 vs 1 fights. I intend to make a multiplayer version of it where 4 or maybe more players can fight each other over the internet.
If you want to try it out, you can download it on itch io for free
