I was thinking for a while that I will add an arena mode. It does include a bit of lore and reworked combat system. You can create your character and fight many waves and bosses. And one of my favorite ideas is the upgrade system. But I don't know if I make the upgrade system how I wanted. But let's hope that I rework combat system a little bit. Only what I did is that I fixed a walking system (a little bit but it is better). The Arena mode will be the last update of my game. Since it is my last scratch project and I want to move to the Unity engine (where I want to remake FNAHB from gamejolt and BMAE.), then I should make my game a little bit better. Generally my game is a bit boring and repetetive (just a walk and fighting simulator.) but it has a very nice story. This game should be relaxing for everyone but if you want me to make a real challenge, then there will be arena mode which will be hard. Here's what I've done, but I will not make a spoiler (another arena mode clip).

And I have another idea... Do you want a Bunker Maniac mode? (The most challenging mode for the game.)
