Games Like Space Invaders: 10 Free Retro Space Shooters to Play Now

Space Invaders came out in 1978 and basically invented the shoot-'em-up genre. Rows of aliens march down the screen, you slide left and right behind barriers, and the tempo builds as fewer enemies remain. It's a design so clean that nearly fifty years later, game developers are still riffing on it.

If you're looking for games that capture the Space Invaders feel — fixed-position shooters, vertical scrollers, bullet patterns, alien waves — here are 10 free options you can play in your browser right now.

1. Galaga Web

Galaga is the most famous Space Invaders successor, and browser-based remakes are widely available on retro gaming portals. The core mechanic is the same — shoot descending alien formations — but Galaga adds swooping attack patterns where enemies break formation and dive at you. The "dual fighter" mechanic, where a captured ship can be rescued to double your firepower, remains one of the most satisfying power-ups in arcade history.

If you want the closest thing to Space Invaders with just a bit more depth, Galaga is the answer. HTML5 versions are available on CrazyGames, Poki, and various retro game sites.

2. Space Destroyers

Space Destroyers is a modern take on the fixed-position space shooter. You defend against waves of descending aliens, but with a power-up system that drops weapon upgrades, shields, and special abilities during gameplay. Boss encounters punctuate the wave-based progression, and the difficulty curve ramps steadily without sudden spikes.

It captures the classic Space Invaders rhythm — clear a wave, brief reprieve, next wave is harder — while adding enough modern features to feel fresh. It plays well on both desktop and mobile.

3. 1945 Air Force

1945 Air Force is a vertical scrolling shooter with a World War II skin. You pilot historical aircraft through waves of enemies, collecting power-ups and dodging return fire. The production values are high for a browser game — detailed sprite work, smooth scrolling, and satisfying explosion effects.

It's further from Space Invaders than some games on this list (you move freely rather than being fixed to the bottom), but the core loop of "shoot everything, dodge everything else" is the same DNA. Available on multiple web game portals.

4. Chicken Invaders

Chicken Invaders replaces Space Invaders' alien formations with waves of chickens. It sounds like a joke, and the tone is deliberately comedic, but the gameplay is solid — the chicken formations use varied attack patterns, drumsticks drop as power-ups, and boss chickens are genuinely challenging.

The series has been around since 1999 and has a dedicated fanbase. Browser-playable versions of the earlier games are available on several gaming sites. If you want Space Invaders gameplay with personality, this delivers.

5. ZType

ZType is a typing game disguised as a space shooter. Enemy ships descend toward you, each labeled with a word. You destroy them by typing the word correctly. Longer words appear on tougher enemies, and as waves progress, multiple enemies attack simultaneously, forcing you to prioritize targets.

It's an inventive take on the genre — the spatial threat model is pure Space Invaders, but the "weapon" is your keyboard. It's also genuinely good typing practice, which makes it one of the few games you can justify playing at work. Available at zty.pe.

6. Astro Party

Astro Party strips the space shooter down to its most competitive form. It's a local multiplayer game where players control small ships in a wraparound arena, each armed with a single bullet that must be fired and retrieved. The one-shot-per-player mechanic creates tense standoffs that feel more like a fighting game than a traditional shooter.

It's less about waves of enemies and more about the player-versus-player dynamics that Space Invaders' competitive scoring implied but never fully delivered. Best played with friends.

7. Galaxian

Galaxian was Namco's 1979 response to Space Invaders, and it introduced two ideas that defined the genre going forward: colored sprites and enemies that break formation to attack individually. Where Space Invaders' aliens march in lockstep, Galaxian's break rank and dive-bomb you, which forces reactive play rather than pure pattern memorization.

HTML5 remakes are available on various retro gaming sites. If you've played Galaga but never tried its predecessor, Galaxian is worth experiencing — it's the bridge between Space Invaders and everything that came after.

8. Phoenix Force

Phoenix Force is a boss-rush space shooter — instead of clearing waves of small enemies, nearly every encounter is a large enemy with complex attack patterns. You choose from a roster of ships with different shot patterns and special abilities, then face a sequence of increasingly difficult bosses.

It's a good fit for players who enjoy the Space Invaders formula but want more spectacle per encounter. The boss designs are creative, and the difficulty is high enough to provide a real challenge. Available on browser game portals and as a mobile app.

9. Bullet Heaven 2

Bullet Heaven 2 is a bullet hell game — the subgenre that takes Space Invaders' concept of dodging enemy fire and dials it up to an extreme. The screen fills with hundreds of projectiles in intricate patterns, and survival requires threading through gaps measured in pixels. Between dodging, you're returning fire with upgradeable weapons and special abilities.

It's considerably harder than Space Invaders, but it's a direct evolutionary descendant. If you've mastered easier shooters and want to see how far the genre can push you, bullet hell is the next step. Bullet Heaven 2 is one of the more accessible entries in the subgenre.

10. Geometry Wars

Geometry Wars is a twin-stick shooter where you pilot a small ship in a confined arena, fighting off waves of geometric enemies that swarm from all sides. The neon-on-black visual style is iconic, and the gameplay is pure arcade — survive as long as you can, rack up the highest score possible.

It's a different spatial arrangement than Space Invaders (enemies come from everywhere, not just above), but the moment-to-moment gameplay — shoot, dodge, prioritize targets, manage screen space — is rooted in the same arcade tradition. Browser-playable versions and clones are available on several game sites.

The Space Shooter Legacy

Space Invaders didn't just start a genre — it established a gameplay language. "Enemies descend, you shoot up" is a framework that's been adapted into typing games, comedy games, RPG hybrids, and competitive arenas. The games on this list span almost fifty years of that evolution, from Galaxian's 1979 dive-bombers to 2026's browser-based bullet hell.

What they all share is the core loop: threats approach, you respond, the pressure builds. That loop worked in 1978, it works now, and based on the number of developers still building on it, it's going to keep working for a long time.
