You have just woken up to find out your floppy disk is full of viruses! Unfortunately, it contains the only copy source code of the game you have been working on in the past months...

Recover the source code before the disk is damaged beyond repair! Luckily, you have an excellent antivirus program, Binary Battle, at your disposal. Use it to destroy all the viruses before it is too late.

Go through the depths of five levels of your disk, kill viruses, upgrade your powers, collect coins and spend them on upgrades, find keys to the encrypted chests and find the exit to the next level. 

Your disk has limited health, which decreases as the viruses attack. Also, each action generates heat, and if your drive overheats, your disk slowly takes damage. 


Binary Battle is a novel take on the dungeon crawler genre. It was inspired by GEOS and the PC game Folder Dungeon. It is compatible with both PAL and NTSC machines.

Kinda reminds of Folder Dungeon (which is great considering this was inspired by it.) I haven't tried this yet though but imma play it later.

A really good game. And an hard one, I do not get to the second level.

Here is a small video I made while I was playing it. I surely need more training to get to level 2 and beyond!



Due to the highly-randomised nature of the game, some runs are more difficult than the others, but in general the game is not that tough. I can beat it almost every time.

There are some helpful hints in the manual, check them out. In the first level heat management is quite important.

I have to read the manual once again. And I'll try again taking care of heat.

How do you play the game?

What do you mean? Load it in a C64 emulator (i.e. VICE) and use 1531 mouse in port 1 or joystick in port 2.

An entertaining representation of computer security in the shape of a combination of dungeon crawler, strategy and point-n-click gameplay. A Folder Dungeon with an aesthetic more in line with the computing of the 1980s and early 1990s.

amazing game!

Unique stuff. Normally I despise black&white games but this is done right. 7/10 imho
