The twin botz are ready to defend their base from the alien invaders appearing from above. You are in control of both of the botz who are present on each sides of the platform. Use the WSX keys to move up, down and increase the level of the right bot respectively. Similarly use the QAZ keys for the left bot. Aim with your mouse towards the aliens and left click to fire laser weapons to destroy them. Try not to hit the lasers to your friendly bot. The health bar is shown beside each bot. Kill several aliens ships to gain experience and increase your level. Don't let those filthy aliens reach your base at any cost.
