Open to any Jeepney.io commander, any country, any rank. No entry fee. First 128 registrants lock the bracket.
Why we're doing this
An open worldwide call, to stress-test the system for real
This is BAKBAKAN's first tournament run on the new Knockout bracket engine — single elimination, seeded by registration order, resolved automatically start to finish. We're inviting commanders from every country to put it through a real event before it becomes the standard for every future Arena tournament.
The prizes
Everyone who registers — and everyone who finishes — walks away with something
Free gear the instant you register, before a single match is played. A serialized Iron Regiment board for every commander once the bracket closes, numbered by exactly how far you went.
Every commander who registers
Philippine Flag + Philippine Army skin, gifted instantly
The moment your registration is confirmed, the Philippine national flag and the Philippine Army branch insignia are added to your Armory — free, no purchase, ready to equip.

YOUR SERIAL №
⚔ Every commander who finishes the bracket
Iron Regiment Board — numbered by how far you go
Every commander who fights in this bracket is struck a serialized Iron Regiment board — gunmetal steel plate under a black-and-yellow hazard-stripe frame — when the tournament ends. Your serial number is your final standing: No. 1 for the Champion, No. 2 for the Runner-Up, and so on down the entire field. Never sold. Never reissued. Awarded only, and yours to keep forever.

What you actually get
Real gear, rendered exactly as it looks in the Armory
