About the game

A roguelike deckbuilder based around designing a microchip from a pile of junk circuits to out compute incoming viruses trying to crash your system. Combo hardware with software programs to chain multipliers that overflow your FLOP meter before the glitches overwhelm you.

Original Steam description

Save Humanity.exe is a microchip building roguelike that pits your deckbuilding and circuit design skills against ever-stronger computer viruses. Only smart placement and combo chains can build the compute power needed to survive the onslaught.

Build Your Microchip

Draw color coded circuit components from your junk pile and place them on the circuit board to build up the compute power you need to challenge incoming viruses. Snap adders, multipliers, batteries, and more together to build up FLOPs and then connect them with wires to build combos and overflow the FLOP counter.

Between rounds trim your deck, raid the shop for stronger parts, and keep upgrading to handle stronger and stronger enemies. Strategic placement, intelligent deck design and maybe a little luck are needed to save humanity from the virus threat.

Combo Hardware with Software

Install programs to layer software bonuses on top of your hardware, then chain them with the right circuits to discover near-endless build combinations and watch your compute power multiply beyond even the most powerful viruses.

Find everything Save Humanity.exe has to offer:

  • 15 different hardware pieces to build the base of your microchip

  • 150 software programs, each with 5 variants

  • 20 consumable items to alter and upgrade both hardware and software

  • 20 different downloadable skills

  • 10 starting characters

  • 34 enemy viruses to overcome

  • 10 difficulty modifiers
