Alternatives to Galaxy Attack: Alien Shooter
By App Store Tracker Editorial · Updated — live App Store data verified
The short version
Galaxy Attack: Alien Shooter is a top-down arcade shoot 'em up where you pilot a lone spaceship, blast alien waves, and upgrade weapons across hundreds of levels. The closest match with real staying power is Galaxiga from ONESOFT, which carries over 25,000 ratings and the same retro Galaga feel. For a similar free option, Doodle Mobile's Galaxy Shooter is a well-reviewed pick. The list ranks by embedding similarity and live App Store ratings.
The app you searched for
Dino Game Limited
If you have cleared the level grind in Galaxy Attack: Alien Shooter, you are probably hunting for the same hit somewhere else: tap or slide to dodge bullets, mow down formations of alien ships, grab power-ups, and upgrade your spacecraft into a screen-filling weapon. Every pick below delivers that classic vertical shoot 'em up loop inspired by Galaga and Space Invaders, with bosses, mission counts, and ship upgrades front and center. The differences come down to depth and polish: some pack tens of thousands of ratings and years of updates, others are lean free arcade clones with a few dozen reviews. A handful run offline, which matters if you play on the go. We ranked these alternatives by embedding similarity to Galaxy Attack's gameplay and description, then weighed live App Store ratings and review volume so the proven games rise above brand-new entries with little track record. Check the price and in-app purchase flags before downloading.
Why it's similar
Both are top-down arcade space shooters where you pilot a single ship, destroy alien swarms, and collect items to upgrade weapons. They share the same touch-to-move, blast-everything loop across leveled difficulty.
How it differs
This one is fully free with no in-app purchases and ships around 60 levels, a smaller package than Galaxy Attack's sprawling campaign. With only 48 ratings it is far less proven than the seed's 600,000-plus review base.
Why it's similar
Both are classic shoot 'em ups built on adrenaline-packed aerial battles, dozens of starships, and thousands of missions defending Earth from alien waves. The core arcade dogfighting feel lines up closely.
How it differs
From Doodle Mobile, this is a paid app with in-app purchases rather than a free download. It is the best-reviewed direct clone here at 4.67 across 2,319 ratings, though its content library is shallower than Galaxy Attack's.
Why it's similar
Both are fast-paced top-down galaxy shooters with 100+ missions, hundreds of invaders, and spaceship upgrades. You move by touch and clear waves of enemies in the same arcade rhythm.
How it differs
This app is free with in-app purchases but has just 3 ratings at a low 3.0 average, so it is essentially untested. Galaxy Attack offers far more polish, level variety, and a massive, trusted review base by comparison.
Why it's similar
Both channel the classic Alien Invader arcade formula with infinite space shooting, striker bosses, and ship evolution using coins and gems. Sliding to dodge bullets while blasting enemies is the shared hook.
How it differs
This paid app with in-app purchases keeps a tight focus on endless survival rather than a long staged campaign. With 69 ratings it is a niche pick next to Galaxy Attack's enormous, well-established player base.
Why it's similar
Both are classic shooting games where you operate a spaceship, dodge bullet patterns, and upgrade with weapons, gems, and coins against huge bosses. The arcade survival loop matches Galaxy Attack closely.
How it differs
A standout here is offline play with no network needed, plus a compact 45-level structure. It is free, but with only 2 ratings it has no real track record versus Galaxy Attack's hundreds of thousands of reviews.
Why it's similar
Both are space shooter arcade games about defending the galaxy from relentless alien air forces, with the same Galaga-style waves and ship combat. The defend-Earth premise is identical.
How it differs
This app advertises 3D offline play as its angle, useful without a connection. It is paid with in-app purchases and currently has zero ratings, making it a gamble compared with the proven, polished seed.
Why it's similar
Both deliver fast-paced top-down shooting where you pilot a powerful craft, battle enemy waves, and upgrade weapons and abilities. Quick reflexes and dazzling effects drive both games.
How it differs
This free app is the most popular alternative in this group at 943 ratings and a 4.5 average, with a strong arcade-and-music presentation. It skews toward shorter dogfight sessions rather than Galaxy Attack's long upgrade-heavy campaign.
Why it's similar
Both are arcade alien shooter games promising infinite galaxy space shooting against waves of enemies, in the classic free space-game mold. The shoot-and-upgrade core is the same.
How it differs
This free, no-IAP title leans on dated 2020-era branding and currently has zero ratings, so it is unproven. Galaxy Attack offers far more refined visuals, ongoing updates, and a trusted community.
Why it's similar
Both remake the classic chicken-and-invader arcade shooter for modern phones, with many planes, fascinating levels, and giant bosses. The easy touch controls and nostalgic arcade feel align with Galaxy Attack.
How it differs
This paid app with in-app purchases is a lighter, more retro-focused take with 77 ratings. It lacks Galaxy Attack's mode depth and the huge update cadence that keeps the seed's player base engaged.
ONESOFT GLOBAL PTE. LTD.
Why it's similar
Both are modern arcade-style space shooters packed with alien invader waves, unlockable starships, powerful bosses, and a strong dose of Galaga nostalgia. The classic vertical shoot 'em up loop is shared.
How it differs
Galaxiga from ONESOFT is the most established alternative here with 25,967 ratings and frequent updates, making it the safest like-for-like swap. Its presentation and content depth rival Galaxy Attack rather than undercutting it.
Every app in our database carries a dense vector embedding derived from its title, subtitle, full description, and category metadata. To find apps similar to Galaxy Attack: Alien Shooter, we compute cosine distance against every other app and surface the closest 60 candidates. The similarity score shown on each pick is 1 - distance/2 clamped to [0,1] — 100% means the embedding spaces are identical, 0% means orthogonal.
We then re-rank the candidate set using current App Store rating and review-count signals so a 4.8-star app with 100,000 reviews ranks above a 4.5-star app with 200 reviews even when their embedding distance is similar. Apps that haven't shipped an update in 12 months are filtered out before re-ranking.
The similarity cache is recomputed weekly. Live App Store data (rating, review count) is verified every 6 hours.
