About this game
The Enemy Is Evolving. So Must You.
Invaders Evolutions transforms the classic fixed-screen alien shooter into a run-based, 100-level arcade survival war with no permanent power creep. You are humanity's last defensive line, fighting through a dark retro-industrial invasion toward the final Mothership encounter.
Moment to moment, it is fast, readable arcade action: slide the turret through incoming fire, carve openings in the formation, and decide when to risk a shot at a high-value spaceship.
But the aliens are not simply gaining more health. Every success, mistake, and missed opportunity can shift the momentum of the war. Hunt high-value spaceships, protect your limited turret reserves, and build humanity's counterattack before the swarm evolves beyond your control.
Control the Arms Race
Survival is not just about clearing the screen. It is about denying the enemy momentum while accelerating your own build.
Starve the Enemy: Letting roaming spaceships escape, losing reserve turrets, or surrendering control of the battlefield feeds alien development and makes later levels more dangerous.
Learned Alien Tactics: Horde Waves are more than pressure tests. Major Horde milestones teach the wider invasion new behaviors, allowing later formations to close gaps, resurrect destroyed attackers, repair damaged units, and attack from new angles.
Punishing Escalation: Escaped spaceships and failed defenses can trigger severe consequences during relevant encounters, including carpet bombing pressure.
Research Humanity's Counterattack
You do not receive every major tool automatically. At key milestones, choose which technology to research next and shape the campaign around your priorities.
Turret Shields absorb incoming hits and help protect your active turret from immediate destruction.
Defensive Barriers reinforce battlefield cover and improve the durability of each barrier section.
Seeker Missiles track roaming spaceships, deny the enemy valuable escapes, and grow stronger through upgrades.
Build, Survive, Score
Between levels, spend upgrade points to adapt your turret for the war ahead. Improve firepower, reload speed, bullet speed, movement, upgrade progress, turret reserves, shields, barriers, and seeker missile performance. Experiment with your build before committing, giving you room to strategize without punishing an accidental click.
At the end of each level, a performance ledger rewards clean shooting, aggressive spaceship hunting, and fast clears. Difficulty multipliers affect scoring, making survival alone only part of the challenge. The strongest runs demand accuracy, speed, smart research choices, ruthless resource denial, and long-term upgrade planning.
A good run feels like holding the line by inches: one reserve left, bombs falling, upgrade meters racing, and one more wave still somehow within reach.
Key Features
100-Level Campaign: Fight through an escalating invasion ending in a dedicated, multi-phase Mothership battle.
Three Difficulty Modes: Learner offers a gentler path for practice, Normal delivers the intended strategic balance, and Valhalla increases alien pressure while doubling your score potential.
Human Research Choices: Choose between shields, defensive barriers, and seeker missiles instead of receiving every major tool automatically.
Evolving Alien Threats: The swarm learns formation optimization, angled bombing, resurrection, active repair, and other permanent battlefield behaviors.
Guardian Encounters: Survive massive, highly durable boss-style enemies that require sustained damage, movement, and mastery of their attack patterns.
Performance Scoring: Accuracy, spaceship kills, clear time, and difficulty multipliers all feed into your final score.
Global and Country Leaderboards: Chase worldwide scores or compete asynchronously for national bragging rights.
Controller and Keyboard Support: Play with controller support across gameplay and major menus, or use configurable keyboard profiles.
Proton-Tested Windows Build: The Windows build has been tested on Steam Deck and Ubuntu through Steam Play / Proton. No native Linux build is currently included.
Retro-Industrial Arcade Pressure
The battlefield blends classic fixed-screen action with a dark mechanical style: glowing projectiles, dense alien formations, reinforced barriers, turret shields, seeker missile trails, Horde pressure, Guardian attacks, final-boss spectacle, and a tense industrial soundtrack built around one-more-wave momentum.

V1.0.2 Invaders Evolutions - Released
Proton Compatibility Update: Steam Deck and Linux Testing Hello everyone, A new compatibility-focused update has been released for Invaders Evolutions. This release confirms that the Windows build has been tested successfully on Steam Deck and Linux-style setups using Steam Play / Proton. This is not a major gameplay feature update. Instead, it is a practical compatibility release to give players more confidence about where and how they can play. Please note: this release does not include a native Linux build. Linux and SteamOS compatibility is currently provided through the Windows version running via Steam Play / Proton. We are not yet eligible for formal Steam Deck certification, so while our testing has been successful, we cannot currently provide that second layer of official assurance. Highlights Steam Deck testing has been completed successfully The Windows build has been tested successfully on Linux through Steam Play / Proton Video playback and audio have been checked under Proton Controller-only play has been checked across the core game flow Steam text entry for high scores has been checked through the Steam input overlay 1280x800 display and text legibility have been checked Steam Deck Testing Invaders Evolutions has now been tested on an actual Steam Deck via Proton and has been reported to run effectively. The game has been checked for the areas that matter most on handheld play, including controller input, readable text, 1280x800 display behaviour, video playback, audio playback, and general gameplay flow. Please note that this does not mean Invaders Evolutions has received an official Steam Deck Verified rating from Valve. It means our own testing and player testing have shown the Windows build to run well on Steam Deck hardware through Proton. Linux and Proton Testing The Windows build has also been tested successfully on Ubuntu 24.04 using Steam Play / Proton. During testing, the game launched correctly and the key media systems worked as expected....Read full article on Community Announcements (foodunit)AnnouncementsOfficial
