KKnD2: Krossfire is the sequel to KKnD released on October 31, 1998. It is set 2179, 100 years after the World Nuclear War. After spending another 4 decades underground, hiding from the first loss against the Evolved, the Survivors rose up to a new enemy: the Series 9. The Series 9 robots are machines that have advanced from their farming origins (having the original programming damaged by the nuclear radiation) and taken up arms against the humans, Evolved and Survivor, who destroyed their precious crops, their one and only reason for functioning.
Gameplay takes place after a world wide nuclear war, on three map-types over land and water: a barren desert terrain, forest areas, or urban jungles. Both the desert and city areas provide artifacts from the nuclear war, namely decrepit buildings and polluted water.
Like other real time strategy games such as the Command and Conquer or Starcraft franchises, the primary objective of the game is to eradicate all other factions on a particular playing map. This is done usually through resource management—oil reserves acting as a power source—and maintaining a base of operations while trying to destroy everything else. Fortifications and turrets can be used to protect a base, as well as making use of natural features such as cliffs or buildings.
There are two methods of gameplay: a campaign mode, and a multiplayer mode. The campaign mode allows you to play one of three factions, fighting through a triangle-shaped map in order to eradicate all other enemies. Occasionally there can be multiple factions. Multiplayer mode allows for connection through LAN(ipx or tcp/ip), serial cable or modem, or a soloplay mode where one can choose between a variety of maps and settings to play a private game.
The Survivors are the remnants of normal mankind that hid in the mine shafts during the First Evolved War. They hid, once they saw that the original war was beginning to go so badly, they have since been digging and building new weapons, new structures, new technologies and new ways of killing. Determined to exterminate the Evolved and shut down the Series 9, they must use their new technologies and units to overcome, overpower and overwhelm the enemy.
The Evolved were on the surface during the 1st Nuclear War and are mutated because of it. While no where near as technologically advanced as their enemies, are they have learned to herd and utilize the power of other mutated creatures, such as large bees and scorpions. The mutants are very religious and believe that their gods (also known as the Scourge) were punishing them for their ignorance, use of technology, politics and the repeated use of TV. The Evolved, to this end, need to eliminate the "symmetrical" (the Survivors) and the "soulless ones" (Series 9) in order to appease the gods. Notably, whereas the other two factions have parallel units, The Evolved have a special "Scourge Demon" unit, at the end tier, which can be constructed by sacrificing 5 infantry units.
The Series 9
The Series 9 are advanced farming robots that have become sick of the Survivors destroying their crops and have taken it unto themselves to destroy all organic life, so they can finally farm in peace. When the Series 9 finally gained their own conscience, they were aware that the other Series robots were still obeying the humans, despite they were gone. They took it upon themselves to shut down the other models in order to complete their goal. While they were active during the first war, they soon realized that their pitchforks and wheelbarrows weren't going to do much against Tanks and mutant Mastodons, taking time to search through Earth's old weapons and wars from history in order to adapt their tools to become formidable armaments. They are farming robots, as such much of their weaponry resembles farm tools, like the Combined Harvester and the Seeder. This faction is new to the game.
Although it was originally rumored that Melbourne House had another KKnD game in the works, they closed down years after the release of KKnD 2: Krossfire. However, die-hard fans have created several mods for games such as Total Annihilation to simulate a "KKnD 3" game.
