About the game
Spectrum Defense reworks a familiar tower-defense setup around the spectrum's seven colors, adding its own twist along the way. Each run scrambles the enemy waves, paths, and map itself, and a freshly rolled Color Table decides how much damage each color deals. Towers can be further customized by fitting them with modules, so players mix colors and modules to find the right counter for each threat. FrostSnake developed and published the game, which released free-to-play in 2026.

FAQ
Are keys from these stores legal?
Buying is legal — keys come from the grey market, so a small deactivation risk exists. So before paying, check the seller's buyer protection.
Which key region should I pick?
Global activates everywhere. Regional keys (Europe, North America, RU-CIS) only work on accounts from that region — use the Region filter to match your account.
What is an activation platform?
The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.
What's the difference between editions?
Standard is the base game; Deluxe usually adds an expansion or bonus content. The edition filter shows exactly that variant, with no mixed prices.
