Galactic War One

Galactic War One is a tower defense game set during an alien attack on Earth. The aliens seek to collect resources from the Sun, so governments unite to develop countermeasures and establish bases in space. After humans resist the invasion, the aliens are forced to leave the Sun.

Build your defenses

You use star iron to build defense towers and gain star coins, which are used to refresh and select towers. You can build only one tower at a time, and each tower must be refreshed. Three types of refresh offer towers of different qualities; higher-quality towers have better attributes. Your choices need to account for the bonds and constraints between towers, since one type of tower alone cannot reach its full combat potential.

Manage resources

You need to use star iron and star coins carefully to win. The game starts on simple mode, and challenging higher difficulties requires enough save cards.
