How co-op works
Up to eight online players defend three-dimensional routes with programmable turrets. The group coordinates infrastructure, targeting logic, upgrades, and coverage across multiple elevations, correcting weak points together as increasingly dense Terrorhedron waves test the shared defense.
About this game
Terrorhedron Tower Defense wraps the classic tower defense formula around a 3D sphere, forcing you to defend from all angles at once. This is true online co-op where up to eight players build, program, and coordinate turrets to survive increasingly brutal waves. The spherical battlefield eliminates safe corners and introduces a layer of spatial complexity rarely seen in the genre.

Turrets can be programmed with custom targeting logic, letting teams fine-tune fire priority and automate responses to different enemy types. Coordinating those programmable defenses with seven other players creates a frantic blend of real-time strategy and teamwork, especially as waves escalate and resources grow tight.
Online co-op is the main multiplayer setup, and sessions are built around constant communication and quick adjustments. Eight-player matches become exercises in shared resource management and spatial awareness, rewarding groups that divide responsibilities and stay vocal when new threats appear.

Frequently Asked Questions
How many players can team up in co-op?
Up to eight players can play together online in co-op mode, defending the sphere simultaneously and coordinating their turret placements and programming.
What does it mean that turrets are programmable?
You can customize each turret's targeting logic to prioritize specific enemy types or behaviors. This lets your team automate smart responses and fine-tune how defenses react to different waves without manual control every second.
Is the 3D sphere harder than flat tower defense maps?
Yes, the spherical battlefield removes safe corners and blind spots. Enemies can approach from any direction, so you need to think in three dimensions and coordinate with teammates to cover all angles at once.
Can I play this solo or is it co-op only?
The game supports both single-player and multiplayer co-op. You can tackle the spherical defense challenges alone or team up with others online.
