Octogun pairs arena shooter action with idle mechanics, casting you as an octopus wielding up to eight weapons simultaneously against endless enemy waves. You accumulate gold, upgrade and merge weapons, and prestige through descents to grow progressively stronger. It appeals to idle fans who want active combat variety and weapon experimentation without demanding constant attention.

About this game

What players are saying

Idle & Incremental Lovers recommends Octogun, with caveats:
Eight "arms" Broctopus brings six "arms" Brotato vibes into the idler genre. Casual take, lots of weapons, numbers go up and clean UI. Pacing is way too slow to be enjoyable in the long run, though.
+ Like said in this short review, the game has a lot of qualities and potential.
+ It's fun to experiment with the different weapons in the first hour of play.
+ Hats for the collectors out there (and some synergies too).
+ My first gripe with Octogun was that a lot of things were unexplained and that I was missing crucial information to understand how the game works (it took me 30 minutes to fully get it). Props to the dev for quickly tackling this point with a patch introducing various tutorial informations into the game!
+/- While technically it's possible to create "builds" and merge weapons, you quickly realize that you can brainlessly progress just by scaling your stats and weapons. I went this easy way, but i admit some people may have fun tinkering with specific builds.
- Some informations are still missing despite the latest patch, but what really bothered me was not knowing how much new skill points I was going to get after prestiging. If you want to create a specific build (or simply finish the skill tree like i absolutely wanted to do) and ultimately fall short because of that, it's pretty frustrating.
- With no enemy variety, it quickly becomes repetitive.
- After prestige, you have to start at wave 1 again, and you don't clear the waves quicker (or very marginally). It would (maybe) still be OK if there was an auto-advance to the next wave (I went to wave 316 before clearing the skill tree, and given you can beat 15-20 waves with the latest weapons you buy, you just sit there, bored, watching your screen and clicking once in a while to go to the next wave... just to do the same thing over again after prestige).
- No ending. I decided to call it a wrap when I cleared the skill tree after 25 hours, but I only really had fun the first 1-2 hours of the game.

This game is a simple but surprisingly satisfying idle arena shooter. The basic loop is easy to understand: defend yourself, collect goldfish, buy better weapons, merge upgrades, level up, and eventually descend to come back stronger.

What I like most is how quickly the game turns from “small octopus defending snacks” into full-on bullet chaos. Being able to equip up to 8 weapons at once gives it a fun “what ridiculous build can I make this time?” feeling. Sniper, minigun, flamethrower, and a bunch of other weapons all push you toward experimenting instead of just buying the same thing every run.

The progression is very much a numbers-go-up loop, so if you do not like idle games, this probably will not change your mind. But if you enjoy upgrading, merging, unlocking hats, and watching your build slowly become stupidly strong, it works well.

It still feels like a small game and I would like to see more content and polish over time, but the core idea is fun.

For my the nicest thing is: try to use the same weapon in all the tentacles, and unlock a hat that matches it. Like spears + medieval helmet.

It gets better
