"In the year 2055, a new war is beginning..." Deep Impact is a total conversion mod set more than 30 years after the events of ZH. Adds 4 new factions: AC, WEA, ADF and WLF.
The fortress acts as the first tier research facility and also as a heavy defense. It researches all tier 2 technologies and unlocks all tier 2 units and structures. It is armed with a huge photon howitzer and 3 Starburst missiles pods. Due to its high construction cost and a limited number of highly skilled technicians and researchers readily available, a player can build only 1 of these structures at a time.
