sort of competitive multiplayer

My english is a bit rusted , french speaker here. But i go an idea about our riftbreaker. Sort of both player in survival mode and it would be possible by item of watever to create some vave in other player biome . it could be implemented in sort of ranked mode with pre construct base and spécial wave . The last player alive win. there could be some risk /reward gameloop , like reaching some point in map to get some powerfull ennemies in other player partie while teleportation range could be reduce to let your base somewhat weaker while you try to erase your oponent . whish you good luck and fun . thomas
