Team up with a friend for co-op missions, or duel them in a 1v1 mech arena.
On a phone: the stick walks (push up to jump), the mech aims at the most dangerous bot by itself, and with Auto-fire on (Settings) it shoots on its own whenever a bot is in range. Clear each area of bots to open the energy gate, then reach the beacon. Every fifth mission is a boss! Hitting bots fills the purple MEGA bar: when it is full, fire the MEGA BEAM to melt everything in front of you. Watch out for shield bots (shoot them from behind or with rockets), boomers that blow up and snipers with red aiming lines. Dash through danger: you can't be hit mid-dash. Some bots drop power-ups: rapid fire, extra power or a full MEGA bar. Mortar tanks show a red ring where their shell will land, and hoppers crouch before they leap. A new Daily challenge every day pays 1 emerald for the first win and has its own leaderboard; the Arena has a weekly one. Beat all six bosses in a row in Boss Rush (Normal or Hard) for a one-time emerald. Collect coins and spend them in the Hangar on new mechs, paint jobs, guns, rocket pods and upgrades.
