About Solar Defense

✦ AI summary

Solar Defense is a tower defense game where you command humanity's defenses against an alien invasion, strategically placing towers to repel the Pilakarr assault on Earth and reclaim lost colonies. Lead a campaign alongside allied generals through a linear story that shifts from pure defense into counter-assaults that require tactical choices about which towers best suit each battlefield.

The year is 2670, humanity has begun its outward colonial expansion into the stars, the HEC (Human-Earth Coalition) began setting up colonies on the Moon, Venus and Mars. upon expanding out into the Exo-Planets they began scouting Jupiter's moon of IO, where they discovered strange readings. This would lead them to discovering another space faring race known as the Pilakarr, a humanoid species that lives on their home world of IO and their outer colony of Europa. The two entities the HEC and the PPU (Pilakarrian Planetary Union) would begin trying to establish economic trade, but a mistranslation led to a HEC trade caravan being attacked by the PPU. This would set off a war between the two nations. The PPU were quick to launch their assault on the desert world of Mars, they would capture the Martian capital of New Olympus within weeks. The HEC Generals are scrambling as the PPU are making their preparations to attack the HEC Capitol of Earth. Take command of the human defenses in a traditional Tower Defense style game. Then repel the invading forces by creating your counter assaults to invade their territory, use military strategy to determine which towers will be best suited for the defenses. Bring home glory for the HEC. Explore a linear story to defend Earth and her colonies and be remembered as a hero, you will work alongside several generals who will aid your journey towards solving this conflict.

Each mission presents a map with predetermined routes that invading forces will follow, and players must carefully decide where to position towers in order to create effective choke points.
