Knights vs Aliens — cheap CD keys, compare prices




About the game
Knights vs Aliens is a free real-time strategy game centered on tower conquest, where players take charge of an unlikely roster of forces - from medieval knights to extraterrestrial invaders and other historically eyebrow-raising factions - competing to seize towers across the map. Across a 30-level campaign, you build up armies and outmaneuver an AI that adapts to your tactics. Developed by Prophetic Sky, Inc. and Eastbridge Game LLC, with the latter also serving as publisher, the game is set to release 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.
