The combat loop

Every decision becomes part of the machine.

LaneLock Protocol turns a tactical card battler into a campaign of commitment. You do not simply clear nodes: you choose which opportunities disappear behind you.

01

Chart a locked route

Read the sector map, weigh battles against markets and upgrades, then commit. The branch you leave is gone for this run.

02

Forge a doctrine

Combine faction identities, Masters, Helpers and modules. Focus a clean strategy or build a dangerous hybrid machine.

03

Command the arena

Deploy cards into limited board space, control initiative and answer armor, flight, heat, suppression and formation pressure.

04

Rebuild after impact

Claim rewards, evolve cards and repair the plan. A strong deck is not the one that starts perfect, but the one that adapts.

Your campaign, your consequence

The map remembers what you leave behind.

Three hostile sectors stand between your starter deck and the final fortress. Battle nodes test your formation; foundries and markets reshape your collection; mystery signals make safe plans unstable.

Inside the protocol

More than one way to build a war machine.

Campaign progression feeds a wider command layer of collection building, constrained formats and recurring challenges.

Seventeen combat identities

Choose a doctrine. Then break it.

Burn through armor with Vulcan Forge, win initiative with Zephyr Wing, anchor the line behind Titan Bulwark or suppress enemy abilities with the Null Choir. Later arcs introduce alien geometry, dark-matter reactors, survivor wreckage and broadcast-ready arena frames.
