Zombie Plague is a Counter-Strike server modification, developed as an AMX Mod X plugin, which turns the game into a Humans vs Zombies struggle. It is based on the original infection mod, but it takes the concept to a new level by introducing:
* New Gameplay Modes: Nemesis, Survivor, Multi Infection, Swarm, Plague
* Zombie Classes System: allows adding unlimited custom zombie classes
* Ammo Packs: awarded to skilled players, can be used to purchase goods
* Extra Items System: allows adding unlimited custom items to buy
* Custom Grenades: Fire, Frost, Flare, and Infection Bomb
* Deathmatch Mode: players may respawn as zombies, humans, or randomly
* Admin commands: can be performed through an easy in game menu
* Special GFX Effects: from the HL Engine
* Customizable Models and Sounds
It brings many customization through CVARS as well:
* Change nightvision/flashlight colors and size
* Adjust in-game light level (lightnings available for the dark settings)
* Set zombies/humans health, speed, gravity, ammo pack rewards, and more
* Enable unlimited ammo or knockback for weapons
* Enable random spawning (CSDM-spawns friendly)
* Separately enable and customize the new gameplay modes to your liking
Enough yadayada... here is the short version:
1- Join the server
2- Choose a team
3- Press m for the options menu.
4- To obtain FREE night vision press m 1 6.
5- To change zombie class press m 2, then choose class.
6- Stay at least 10 feet away from zombies
7- Aim for the head at all times
8- Frost grenade will freeze zombies, at the same time they won't take damage from humans shooting. However, using incendiary grenades will degenerate their health even when frozen.
9- Don't block your teammates!
10- If you happen to become Nemesis, press forward, ctrl and space bar for super jump.
11- While playing plague mode maintain a distance from other humans (if you're still human), infection bombs tend to turn the tables quick when a group of people are too close to each other.
Have fun eating brains.
