Solar Siege is a free Android game developed by Origin8 Technologies Ltd. that lets you become the commander of a deep space mining station. Your main goal is to construct defenses to protect your miners and harvest the riches of the cosmos. You must manage your power network to sustain operations and defend against an alien foe who wants a piece of the galactic pie.

The game offers an arsenal of defensive, supportive, and combative units at your disposal. You can construct an efficient power distribution for a fully operational network. The game's structured campaign spans across 18 perilous parts of the galaxy, where you'll battle against a hostile and well-equipped extra-terrestrial foe. You can take the fight to them and unlock and research new abilities, weapons, and defenses.

Solar Siege offers daily missions to increase your rewards and spend your earnings on a selection of persistent upgrades to support and complement your units. The game also includes Google Play Services for achievements and music and SFX by Gavin Harrison. In-app purchases are optional accelerators, and there is nothing locked or timed to force you to pay anything. The first five game levels are freely accessible, and then each new level can be unlocked for in-game currency earned through normal gameplay or daily missions.
