When you start a game you will have to regain control of the infected planets in the solar system. Once you have colonized a planet, build on its surface by switching from a planetary to a space view without loading screens. Enjoy an epic campaign mode or prove your worth in the infinitely replayable skirmish mode. <img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3171790/extras/e8763e488598e9e65492e61f10fa498b.webp?t=1769153144" width=600 height=20 /><img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3171790/extras/6f5256e557215aabc07116f164f438a1.webp?t=1769153144" width=615 height=50 /><video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3171790/extras/87ab99c98a4f4d4fa1e6e70361ea4aba.poster.avif?t=1769153144" width=600 height=270 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3171790/extras/87ab99c98a4f4d4fa1e6e70361ea4aba.webm?t=1769153144" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3171790/extras/87ab99c98a4f4d4fa1e6e70361ea4aba.mp4?t=1769153144" type="video/mp4"></video><ul class="bb_ul"><li>Face an endless horde of aliens who seek only to infect all worlds in their path.</li><li>Create lines of defense between your planets, take advantage of the coverage of asteroid belts, place energy shields, deploy space turrets and fight against extinction.</li><li>Go on the attack at the right time and reconquer planets to increase your production lines.</li></ul><img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3171790/extras/a71eff66edeeafa3a74c54f12701c130.webp?t=1769153144" width=615 height=50 /><video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3171790/extras/aeb986c86dccdcbc3829e363b768d2ed.poster.avif?t=1769153144" width=600 height=270 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3171790/extras/aeb986c86dccdcbc3829e363b768d2ed.webm?t=1769153144" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3171790/extras/aeb986c86dccdcbc3829e363b768d2ed.mp4?t=1769153144" type="video/mp4"></video><ul class="bb_ul"><li>Reconquer worlds infected by an alien plague.</li><li>Explore solar systems and find different types of planets, from icy worlds to desert wastelands.</li><li>Build on the planetary surface and return to the space view without loading screens!</li></ul><img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3171790/extras/bfe33c67d8fd6d84ba882f0617eb8bed.webp?t=1769153144" width=615 height=50 /><video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3171790/extras/fdceb194271cbdb8a161eba26347a0f4.poster.avif?t=1769153144" width=600 height=270 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3171790/extras/fdceb194271cbdb8a161eba26347a0f4.webm?t=1769153144" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3171790/extras/fdceb194271cbdb8a161eba26347a0f4.mp4?t=1769153144" type="video/mp4"></video><ul class="bb_ul"><li>Embark on an epic campaign in which you will have to regain control of several solar systems around the galaxy.</li><li>Prove your worth in skirmish mode.
