Robot Arena/YMMV

• Cult Classic: There is a small but dedicated group of people who play Robot Arena 2, they also hold tournaments online and make mods for the game.
• Game Breaker: Dear god, this. An engine on top of another engine lets you reach absurd rotation speeds, combined with a spinner resulting in dealing game breaking damage.
  • These aren't terribly compact or lightweight, and due to the way the game calculates damage are vulnerable to damage. They also take MUCH longer to spin up than normal spinners. In general, robots built with glitches are powerful, but they're also glass cannons.
  • Revolving sledgehammer arms. A recent discovery of mine.
    • Iron Spikes would be better weapons.
• "Stop Having Fun!" Guys: The heavyweight 36 mace spinning robots which are actually really common among users. "Popups", or wedged bots with weapons in place of flippers, might also fall under this.
• The Scrappy: EMERGENCY also. It WILL annoy the hell out of you when using something else than a wedge.
