Stroids - Drive your spaceship in the universe to collect resources to upgrade equipment to destroy the enemy

Strategy meets Action in this blockbuster blast from the past. Command your ship to take out enemies and gather resources. Then use those resources to build and defend a base to take shelter in for later waves. Hold off as long as you can against new enemies as you fortify your stronghold with self-firing turrets, strong walls able to withstand heavy enemy fire, and your own fleet of resource gatherers.

Enemies in the first couple of waves are weak and easy to kill. Use this time to gather resources and scout around the map for a good place to start your base. A cave section with two narrow entrances is preferential. Make sure your gate is upgraded, it is the only barrier between you and the enemies. Early waves can be defended without towers. Well placed towers in later levels can help significantly reduce the number of enemies causing damage to your base. Upgrade towers to improve their speed and give them homing missiles.
