Knights vs
Aliens.

Defend Medieval Europe from an alien invasion historians agree definitely happened. Originally an iPad game from 2009, shipped under my old studio Prophetic Sky; rebuilt in Godot and free on Steam July 2. Still the same weird little real-time tower game.

How it works

One rule, eight armies:
kill anything green.

01 / FEATURE

Drag-to-attack combat

Every tower generates units over time. Drag from a friendly tower to an enemy one to send a squad.

02 / FEATURE

Eight playable nations

Five angry European nations — or mind-control the aliens and conquer Earth yourself, for science.

03 / FEATURE

Thirty campaign levels

Three difficulty settings and a dynamic AI that notices when you're doing too well and becomes professionally upset.

04 / FEATURE

Environmental modifiers

Fog of war. Darkness. Sunset battles. Three conditions famously solved by panic.

05 / FEATURE

Also: bears

Don't let the world get eaten by bears. Unlocked the hard way, deployed at your own risk — bears are notoriously reluctant to follow orders.

06 / FEATURE

Nine hidden cheat modes

Nine unlockable modifiers earned through the campaign. Ethical deployment under advice of counsel is recommended.

Captures

From the field.

Campaign battle — squads streaming between towers across a forest map, attack lines mid-flight. SHOT 01 · CAMPAIGN
Winter map — blue armies holding towers across snow and rock. SHOT 02 · WINTER FRONT
Dark-mode battle — lantern-lit squads advancing through blacked-out terrain. SHOT 03 · DARK MODE
Alien nation swarming a King of the Hill map in purple and green. SHOT 04 · ALIENS
Bears loose on a maze map of stone paths and towers. SHOT 05 · ALSO: BEARS
Main menu — knight and alien face off. To battle. SHOT 06 · TO BATTLE

A small thing, kept alive. Free forever.

Coming Soon on Steam now; the release lands July 2, 2026 — free forever, because Medieval Europe has suffered enough. For what Eastbridge is building next, see Animus: Convergence — the first of the Animus titles.
