About Core.Sys

Core.Sys is an action puzzle game about hacking through increasingly complex computer systems. You move a cursor around a 5x5 grid of alphanumeric key panels, scan to identify the next piece of code and select the matching panel to complete the sequence. Each completed sequence bypasses a layer of security and grants access to the next.

As you hack deeper, firewall sweeps become more intense. You must locate the data you need to extract and avoid the firewalls and security sweeps.

Frequently asked questions

Steam lets publishers create keys to sell in other shops. Once you activate a key, the game is yours to keep, just like a store purchase.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
