What do you mean high walls are not cover? You have guests firing through them?
Multiple gun types in a single arena are part of my plan, have to figure out a way to implement it without the UI becoming too cumbersome.
More arena types also part of the plan.
And injuries is something I'm looking into, probably not going to add deaths since that would be a bit too hardcore but I'm thinking about guests getting injured and having to go to a hospital building.
Cheers!

Yes Guests are shooting thought them. i was doing the Royale arena and they are all seperated by high walls into an arena area (So it is an arena inseption) and they shoot eachother through the walls

I'm seeing guests shoot through high walls too. I put health behind two high walls and whomever goes for health almost always dies because the other guy shoots through the wall at them.
