Capture the Flag is team objective PvP: steal the enemy flag and return it to your base while defending your own. Maps emphasize bridges, mid control, and flag carrier protection.
CTF shows up as a mode inside minigame hubs more often than as a dedicated IP. If a listing is CTF-only, expect a smaller but more focused player base.
Class kits (attacker/defender) appear on some networks; others are free-for-all loadouts.
