Seasonal CTF competition
From registration to the final — missions get progressively harder. Compete solo or as a legion.
Create your own legion or join an existing one — leader and member roles, join by request.
Each member's score adds to the legion's total; the legion climbs the leaderboard.
Direct competition with other teams, team chat, and notifications.
From Yigit to Xoqon
RXP is earned from your CP, CTF, DevOps, and learning scores. The square root of each track's score is combined, keeping growth fair.
