in pvp.mod.gml line 16 "global.hpgain = 2" sets how much hp to add each level, change the 2. in pvparena.area.gml line 712 "GameCont.hard+=1" sets how much to increment the weaponlevel each time a chest is destroyed. change the 1 (in the normal game GameCont.hard is incremented by 1 each time a portal is entered. so spc/ultra weapons start dropping around 16. also controls enemy density i dont remember if that matters in pvparena spawning). any text editor will work i recommend notepad++ or gmedit
