About Firewall: Defend The Grid Demo

Become a hacker building cyber defense systems in this retro-futuristic tower defense strategy game. Build your firewall using limited compute power and sector space, connect mods, fight along your defenses running ad-hoc programs and expand to new sectors to protect the Grid from ever-growing chaos.

Follow the main path or do a side mission - it's up to you.

When you have everything you need, use your Hacking Deck to connect yourself to the Grid and start preparing your defenses.…
