Orbit Blade

Orbit Blade is a space action roguelike in which your guns fire automatically and combat continues between waves. You control movement, aim skills and choose cards as you fight through five acts, each ending with a boss. Runs can last up to 35 minutes.

A fleet and its hulls

A fleet left port and never returned. Its guiding star went dark, and its ships found five ways to keep going. TEMPEST is the sixth: recovered, rebuilt and launched again.

You can play as either of two hulls, each with a different approach. TEMPEST uses lightning; when two of its skills meet on the field, they create a third effect. WRAITH uses time, gravity, quantum effects and annihilation. Each hull has six active skills and two ultimates, all available from the start.

Five acts

Each act brings an enemy tide and a boss. After acts one through four, you return to the harbor, where time stops and you can repair, use the black-market slot machine or buy from the shelf before setting out again. Defeating the act-five boss wins the run.

Sectors and enemies

Each run places you in a random sector, where one faction remains your opponent for the whole run. The five factions include a graveyard fleet of bones, a forge that burns and detonates, a choir that fires on a shared beat, a rift that marks its landing spot before jumping to your flank, and a hive that grows faster and more aggressive as more of its kind stay alive. Across them are 88 enemy types and 14 bosses. You can shoot a boss's turrets off to claim the guns they drop, or overheat its armour to stop it firing.

Weapons and upgrades

At a set level, each active skill takes a protocol that determines how it develops. The game has 21 base weapons. Once per run, one can super-evolve into a new form, or take a cross-system form with the right recipe.

Between runs, you earn starlight to light up the star map and unlock new weapons, 16 ship protocols, the harbor forge and danger levels 1–7.

Changing battlefields

Battlefield conditions include meteor tides, radiation fog, gravity wells, wreck shallows, crystal gardens and ion currents, each with its own rules. Kill quickly enough and you awaken the hive, bringing a full swarm tide after you.

Co-op for four players

Online co-op supports one to four players, with up to four hulls in the same sector. You can invite friends through a Steam lobby, join using a four-digit room code or play over LAN.
