I'm planning for Beta 1.10 to be a bigger more polished PVP update. In the meantime I've been quietly patching up bugs and making fixes to 1.09 while also slowly introducing the gameplay and cosmetic changes that will define Beta 1.10. So here's what's new for now.
-"Add Bot" option now available in Custom Matches
--Players can now play 1v1 For Kills against bots on all PVP arenas without having to go into the demo
-TBS increased on the Crossbow
-Rifle max ammo lowered to encourage more Defenestrator and Doob Tube use
-Health bar back in Competitive settings
-Small updates to Horizon and the Asymmetrical Arena
-Cool down time between wall jumps lowered
-Projectiles exist longer, specifically bottles and doobs shot into the air will now land
-Camera movement when crouching in the air removed
-Enemy Killed Icon added to PVP
