Cosmo Tank is a space tank battle game. You're the commander of the tank "Tiger Alpha-1", and your mission is to fight on land and in space against the Master Insect and his minions. The game features both top-down levels and first person levels in which you can freely move around in all directions. Settings feature both open outdoor environments, caves and space. Slowly upgrade your cannon and armor as you progress for more firepower and the ability to sustain more hits.
Alyosha improves on tool23's run by nearly 2 minutes by properly upgrading the laser weapon, better RNG manipulation, and better optimization.
