Battle to become the biggest and baddest orb in Entropy, an IO game in which you collect orbs to grow more powerful, and shoot at anyone who opposes you.
WASD moves your character, and aim and shoot with the cursor. Collect any colored orbs littered about the map to level up, allowing you to invest in attributes such as damage and health.
Killing other players is the fastest way to travel up the leaderboard, but if you're patient (and really good at surviving) you can climb by playing passively and collecting as many orbs as you can.
