A new beta of Delta CTF has been released for Quake 4, now compatible with the 1.3 point release. The Delta CTF team is hoping to be completely sure the mod is stable and ready for competition before the DeltaCTF 1.0 release. If you find any bugs, be sure to post them on their forum or jump on ETG and let them know in #deltactf.
