With the new playtest, crossfire mod needed to be updated as well. Which has been done, but it is not going to be playable for a while as I want to add a few single player missions, sounds, effects and fixes.
The graphics, especially explosions are being updated and one such sprite might be seen in the preview image. not all effects fit well with the game so this might take some time and some effects might not get replaced after all.
If you liked the mod and want something changed, be sure to write a comment or two on the mod page so that I can make changes if I like the suggestion
