The Zombie Panic team has been hard at work, but would still like to bring the fans features that they have requested. And at the same time, we know that variety adds a little spice to the mix.
Therefore, we have just released ZPS v1.6, which introduces several features. Features include a new gameplay mode called "Hardcore" mode. The round is shortened to five minutes, and difficulty is increased extremely for the survivor team. This mode can be enabled via a cvar, or via a map name's prefix. Below are a few screenshots showing off one of the more startling enhancements in hardcore mode, as well as the timer.
In addition to this feature, we have added double-width slots for large weapons (visible in the screenshot above), chatbox messages that indicate who issued a voice command, and a few features to eliminate current gameplay exploits. A full changelog can be found here
