About Radiant Defense
Radiant Defense is a tower defense game set in a vibrant universe invaded by alien hordes. You build a space fortress, place weapons and traps, and defend it through more than 300 waves across 14 missions.
Shape the battlefield
Modules let you alter the aliens’ route, directing them toward your cannons and keeping them within range of your energy weapons for as long as possible. You can also place Proximity Mines at any time to deal with crowds, damage heavily armored units or respond to a critical situation.
Weapons and defenses
The game has 9 upgradable weapons and 3 superweapons. Their abilities include:
- Typhon Fury Flamer: sets passing enemies on fire and quickly incinerates groups of smaller units.
- Seraphim Missile Launcher: fires target-seeking missiles over long distances that explode on impact.
- Power Blades: cut passing enemies and quickly remove their force shields, weakening groups and finishing wounded runners.
- Brightmark Searchlight: marks targets to make them take up to 200% damage from other weapons.
- Omega Cannon: targets any spot and disintegrates everything passing through it. It works well with the Recuperator and Brightmark Searchlight.
- Proximity Mines: explode among enemy crowds or damage heavily armored units.
- Psionic ocular: terrifies enemies, making them easier targets; it works especially well with superweapons such as the Omega Cannon.
- Recuperators: collect twice the money from nearby alien kills. They work well with area-specific weapons such as Proximity Mines and the Omega Cannon.
