About MEGAPAIN: Retro FPS Shooter 3D

Megapain is a Serious Sam-style arena shooter for Android from BARS Interactive — angular 3D mutants in hordes across desert canyons and ruined labs, a story set 100 years after the apocalypse, a rock soundtrack, an offline campaign and an online mode for eight-player co-op or deathmatch — free with ads and packs from $0.99 to $4.99, at version 0.8 as of July 2026. It has 1,470 Google Play reviews at 4.5 and no iOS version. Doom veterans call it a long, flawless throwback; the one complaint is that gun upgrades lean on watching ads.

Megapain Review: Serious Sam's Hordes on Android, Free, Still at Version 0.8

Ten Monster Types, Hordes on Screen, a Plasma Cannon in Hand

The design is the 90s arena shooter as the listing describes it — angular 3D, no pixel art, rock guitars, no filler — and the model is plainly Serious Sam: open desert arenas where dozens of mutants charge at once, each of the ten-plus types with its own attack and weak point, met with an arsenal from pistols through rocket launchers to plasma cannons. There is a story — a return to Earth a century after the apocalypse — told across a campaign a July 17, 2026 five-star expected to speed-run and found going level after level for hours, still unfinished; that reviewer grew up on Doom, Hexen and Quake and calls the game a flawless gem. The July 28 update added a level, achievements and visible damage on monsters. Offline solo play is the core; an online mode adds co-op for up to eight and PvP deathmatch on dynamic arenas.

Version 0.8, Ads for Upgrades, and Bosses That Deserve More Use

The reception is small and warm, with one recurring economy note: a May 28 five-star with two votes wants new levels, bosses and guns, more difficulty even on the hardest mode, and objects that improving a gun means watching ads — a very bad thing in the game, in that player's words. Retro Wave Publishing, the Cyprus publisher, replies to every review. The version number, 0.8.1.3, says the campaign is still being built, and the reviews treat it that way — requests rather than bug reports. What is missing from the record is any critical voice: the three visible reviews are all five stars, and 1,470 ratings at 4.5 from 10,000-plus installs is a committed niche rather than a crowd.

Free With Ads, Packs to $4.99, No iOS — and a Data Card Larger Than the Price

The game is free with advertising and in-app items from $0.99 to $4.99 — gun upgrades and ad removal, on the evidence of the May review — and there is no iOS version or App Store listing. The data card is the note: Google lists location, financial info and three other types both collected and shared with third parties, which for a mostly offline retro shooter is out of proportion. The floor is Android 7.1; no size is published; rated Teen for violence and blood, with the online mode flagged for user interaction. Prices are regional.

Pros

  • Serious Sam-style hordes — ten-plus mutant types with weak points — on a phone
  • A campaign long enough to surprise a Doom veteran who meant to speed-run it
  • Offline solo play plus eight-player online co-op and deathmatch
  • Fast, angular, guitar-driven — the 90s vibe done without pixel art
  • Free, with packs that top out at $4.99 and a publisher that replies

Cons

  • Gun upgrades that lean on watching ads, per the one critical note
  • Version 0.8 — a campaign still being built, with bosses underused
  • Android only — no iOS version, and no size published
  • Location and financial data shared with third parties for a mostly offline game

Verdict

A 6.0: a free, fast, honest Serious Sam-alike for Android with a longer campaign than its store page suggests and a small, happy audience — held to version 0.8, gated in places by rewarded ads, and absent from iPhone entirely. Take it if you want 90s horde-shooting on a phone and can live with an ad for an upgrade. Skip it if you are on iOS, or if location and financial data shared for a retro shooter is a line for you.

Gameplay7Horde arenas with loot and secrets that keep going; difficulty a fan wants raised.
Controls6Twin-stick touch shooting that no reviewer faults or praises — the genre's usual compromise.
Replay value6Difficulty modes, achievements since July, online co-op and deathmatch; more levels still arriving.
Graphics & sound6Angular mutants and orange skies with visible damage now, and a rock soundtrack that fits.
Monetisation5Cheap packs, but ad-gated upgrades and an oversized data card.

Frequently asked questions

1

Can you play Megapain offline?

Yes — the listing leads with no internet required, and the offline mode is the solo campaign with its survival-horror pacing. Online co-op for up to eight and PvP deathmatch need a connection, as do the rewarded ads that a May 2026 reviewer says gate gun upgrades.

2

Is Megapain free?

Free with ads on Google Play, plus in-app items from $0.99 to $4.99 — gun upgrades and ad removal, by the reviews' account. A May 2026 five-star objects that improving a gun means watching ads; no reviewer objects to the prices. There is no iOS version. Prices vary by region.

3

What phone do you need for Megapain?

Android 7.1 or newer; the publisher does not list a size or recommended hardware, and none of the most-voted reviews reports performance trouble with dozens of monsters on screen. The angular retro style is light by design. There is no iPhone version.

4

Can you play Megapain with friends?

Yes — the online mode offers co-op for up to eight players and fast PvP deathmatches on dynamic arenas, per the listing, and Google Play flags user interaction. The campaign is solo; the reviews focus on it rather than the online modes.

5

How long is Megapain?

Longer than it looks: a July 2026 reviewer who expected a short speed-run was still finding new levels after hours, and the July update added another. At version 0.8 the campaign is still growing, and difficulty modes, achievements and the online modes extend it for anyone who wants more hordes.
