Graph TD: Cosmic

Graph TD: Cosmic is a tower defense game set at the end of the universe. You pilot the “Graph Theory” through time and space, fend off an invasion of exotic biological substances and try to reverse Earth’s fate. You deploy nodes, distribute power and manage heat, while making plans around random, limited resources.

Strategic defenses

You arrange nodes and towers according to graph theory logic. Towers can be upgraded along different paths, changing their roles from support to main damage output. Driver cards can be combined and upgraded, then placed inside defensive towers to give them various bonuses.

Spacetime scenarios

Scenarios range from the end of time to neutron star orbits, with enemies taking various forms. The game uses approximate simulations for spring grids, heat and electric current; these systems are not scientifically accurate.

Companions and loss

You can choose a character to accompany you through the co-pilot system. The game also has a permanent-death roguelike mechanic: if the “Graph Theory” is lost, your consciousness is teleported back to the end of time.
