Slain.io is a highly addictive Multiplayer iO game where you will experience lots of tough challenges and try to survive all dangers. You will kick things off as a weak player who has to stay watchful for the deadly spiked NPCs and the stronger opponents while trying to roam around the map. Make sure you stay alive longer and never stop increasing your power through over time. Use your basic weapons first to kill the enemies from afar, pick up more orbs, upgrade your stats, prolong your life and take over the highest rank on the leaderboard. Have fun!
