Sektori is a tense twin-stick shooter designed by Kimmo Lahtinen that combines frenetic arcade action with pounding techno music. The game offers fast-paced progression through five dynamically changing worlds filled with diverse enemy waves and evolving bosses that transform during combat. Players choose different ships and customize upgrade decks to create a powerful build that suits their playstyle. Each run offers a unique combination of handcrafted attacks rather than predetermined sequences.
