There is a cure for this, and its name is D2X-XL. D2X-XL offers a full-blown CTF mode (dubbed "CTF+") with the following features:
- Flags will always spawn in their home base after scoring
- A team can only score when their flag is in their home base (i.e. flag goal)
- A team can return their flag to its home base by touching it
- DLE-XP and D2X-XL offer team-only spawn points: Players of a team will always spawn at one of these spawn points
I hope this sounds like a good reason to play your next multiplayer game using D2X-XL. You can find a CTF+ map here. As a cherry on top of the cream this map supports up to 16 players.
