Our take on Trigonarium

The focus on demanding arcade combat gives the game a clear action structure, but may leave less room for players who prefer low-pressure pacing or sessions built only around short challenges.

What is Trigonarium?

Trigonarium is a challenging twin-stick shooter with arcade-style combat.

Players fight through enemy formations in changing battle arenas and face large level bosses. The game includes an original campaign with 3 worlds and an ultimate campaign with 5 worlds.
