About Negative Energy

Negative Energy is a tower defense game with basic RTS mechanics. You defend the construction of a Dyson sphere until it is complete, building ships and directing fleets around the star system to intercept and destroy enemy forces.

Command your fleets

Build ships and assign them to fleets, then plan when and where to intercept enemy attacks. You can move and attack with your ships to seize the initiative, and reassign ships to other fleets.

Manage resources

Gather and manage available resources to build better ships. You can pause the game at any time.

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.
