Dodge waves of enemies trying to stop you from carrying their flag back to your base.

Capture the Flag

Sneak up to the enemy base and capture their flag by touching it. Delivering the flag to your base scores a point for your team. If you are killed while holding a flag, it will automatically be returned to the enemy base.

Your team's flag must be at your team's base to deliver the enemy's flag, so wait until the enemy's flagholder is roasted before making the delivery.

Changes

CTF plays the same as in unpatched JJ2, but better:

Details for Running a Server
Details for Level Designers

Your level must have two CTF Base events, one with the Team parameter set to 0 (Blue) and one set to 1 (Red). You should also include Multiplayer Level Start events, some with Team as 0 and others with Team as 1.
(Nearly) symmetrical layouts are generally preferred, so the teams have equal chances of winning.

Backwards Compatibility

Clients running JJ2+ v0.1 through v6.3 see gold asterisks instead of flag icons.
