So I simply watched the IGN video about the map "Endless Vale" in the Destiny 2 beta. I thought it looked fun and simple, so I spent a few hours to see how close I could get it from just that video to what it ends up being. I think it will play decent with Halo's mechanics but may have to change a few places.
Spawns and weapons are on there, but not much testing as all. Grenade launcher is only power weapon, with some shotguns to help.
Open to any suggestions but I imagine I may change it after the beta with better dimensions.
