Scavenge your way to the top of the leaderboard in Scavs.io. You start with only a knife and your wits. Destroy containers to look the contents. Sell that to make money. Then equip yourself with deadly weapons and protective armor. Then kill everyone else inside the danger zone.
Move with WASD. Shift sprints. Pickup items with E. Attack/Shoot with left click. Reload with R, and stealth with C>
If you're in danger, high tail it to the safe zone. (The danger zone is signified by the red line.)
