The very first playable version of the mod.
List of possible bugs:
1. Turrets may be stuck defenseless depending on their placements on the level proper.
2. Invasion mode may result in the player getting telefragged by the spawning zombies.
3. Mines and turrets can only harm the player and the zombies, but not other human NPC's (this will be corrected in the future).
4. The color translation of NPC's is carried over to their burning sprites.
You'd be forgiven to expect fighting ordinary demons in this mod; this may or may not have actually been the case.
A strange virus of unknown origins (some speculate it came from Hell itself, others believe it was manufactured by UAC) got loose, and wherever it spread, chaos and destruction came along. The victims died where they stood, then stood back up as zombies and started to attack anyone who was close to them.
The situation got worsened by some infected mutating and gaining new combat abilities; rumors were that certain monsters violently exploded on contact with their prey, some could stay invisible and invulnerable for a long time during their hunt and there were even sightings of zombie dogs prowling around! To make matters worse, some surviving humans banded in two different camps. One group was trying its best to help out human survivors and protect them from the undead, while others merrily placed traps and ambushes for any unsuspecting victim to fall in, whether human or undead. Was it all caused by materialism? Or was it a classic case of paranoia and inability to get along with strangers? Whatever it was, you now have to make your way through the familiar levels of Doom, Doom II and their respective expansions, all while hoping that you will make it to the end in one piece.
Key features:
1. All enemy spawn points are replaced by zombie spawners; depending on options the player chooses, different kind of monsters may spawn.
2. Zombies can be taken down with a single headshot, though at times they might be more resilent to that. Otherwise, they will stay down for several seconds and then come back up again.
3. There is a probability of finding a marine in the depths of the level (or right off the bat if you are lucky), said marine will be either a good trustful ally or an aggressive marauder who will gladly gun you down on the spot. On easier difficulties, you will be able to tell a good marine from an evil one by color, but on others you will have to take risk each time you find a fellow human that is not player-controlled. You will also encounter ordinary human survivors who are helpless and can't really fight back against the undead. Press the USE key to extract them to safety; you will be rewarded with a random item they can drop, ranging from meager health & armor bonuses and up to a rocket launcher or mega armor.
4. Every time you play, the enemy and obstacle placement is changed: be careful around possible landmines and watch out to not get riddled with bullets from a random security turret.
5. Zombies are hated by both ally and enemy marines alike, creating the all-out war scenarios at times.
6. Six levels of difficulty, the last one ("Arcade") offers a whole new scenario entirely, making the randomizer go off the rails and make the game even more unpredictable. Another gameplay mode ("Invasion mode") has the whole map gradually populated by the undead who spawn endlessly as you go along - make sure you escape the place alive and in one piece!
7. Compartibility with a lot of weapon packs. Goes best with "Brutal Doom", "High Noon Drifter", "Shut up and Bleed" and many others.
8. If a certain option has been switched on, the player will rise back as a zombie NPC upon dying; afterwards they will attack other uninfected humans, including fellow players. No matter where or how you die - if your body does not get destroyed in time, you become one of them, end of story.
9. The whole scenery comes to life the second you enter the map, no one is waiting for you. Everyone is minding their own business, be it zombies attacking turrets or a small squad of marines defending themselves in a small cramped room with little hope of salvation. For example, you hear the fight going in the distance, but upon entering that room and finding a bunch of undeads (some of which had already been put down) and a couple of discarded guns, you realize what truly happened there. Or when you finding marines fighting zombies and ponder on whom to shoot first or if these could be your allies.
10. Several zombie types: some serve as mini-bosses, some are made of fresh marines (players and NPCs) and there are also zombie dogs which are fast and deadly if not taken care of immediately. Rumors were of white zombies, the top dogs of the group who have the ability to revive their fallen brethen and bring them back to combat.
11. The additional music pack is designed to bring suspense to the level, along with ambient sounds and the whole map potentially being darker than usual (can be customized through CVAR's).
12. Both marines and zombies will apply to any title screen regardless of what WAD is being used.
Port: GZDoom/LZDoom/Zandronum.
