About this game

🎮 Download the FREE retro FPS shooter - no internet required! MEGAPAIN is an oldschool 3D action game inspired by classic arena shooters of the 90s: fast-paced combat, story-driven campaign, hordes of monsters, and the authentic vibe of legendary PC hits.

WHY PLAYERS LOVE MEGAPAIN:
✓ AUTHENTIC RETRO STYLE - Angular 3D graphics, oldschool aesthetics, rock soundtrack, and pure gameplay without filler - just like the legendary shooters of the past. No pixel art - just pure nostalgia!
✓ 10+ TYPES OF MONSTERS - No generic zombies here, only unique mutants and giant bosses. Each has distinct attacks and weak points to discover!
✓ CHAOTIC ARENA BATTLES - Face overwhelming hordes of enemies on screen at once. Only tactics, reflexes, and precise aiming will save you from the apocalypse!
✓ TWO WORLDS IN ONE GAME:
• Offline Mode - Solo survival against AI with survival horror atmosphere. Every bullet counts!
• Online Mode - Team up with up to 8 players in co-op or compete in fast-paced PvP deathmatches on dynamic arenas.
✓ DEEP GAMEPLAY - Massive weapon arsenal (from pistols and rocket launchers to plasma cannons), secret areas, and unique mutant bosses to conquer.
✓ STORY WITH A MYSTERY - 100 years after the apocalypse, you return to Earth to uncover the truth: is it safe now? Secrets of ancient laboratories await brave explorers...

Thought I'd give MEGAPAIN a quick speed run play, thinking it was a only short game. How wrong was I !! Level after Level, it just keeps on going to another level after hrs of play..and there is still more levels I will conquer. I grew up playing doom,hexen,quake etc, this gem of a game is flawless, excellent controls and options. Takes me back. Great game, very well made dev 👍

add new level and bosses but one thing is that didn't use the boss like a monster in the levels and add some hardness in the game i literally play very difficult mode and I'll definitely be waiting for new guns and if I need to improve my gun I used to watch ads it's a very bad thing in the game you guys have to fix this infact introduce some kind of point system by killing the thousand of monster in game you only got level clear and nothing and you guys made a gem please publish it and thnks
