Complete & Enhanced Mod Description
Mod Name: CS 1.6 Zombie Shelter (based on CSO/CSNZ)
This is a comprehensive survival-horror conversion for Counter-Strike 1.6 that faithfully recreates the "Zombie Shelter" mode from CS Online and CS Nexon Zombies. It features unique gameplay, deep customization, and addresses a core engine limitation with a dedicated plugin.
Core Gameplay & Features
-
Objective: Survive against escalating waves of zombies. Win by either radioing for help or killing the scenario's boss zombies.
-
Progression System: Difficulty increases over time ("days"). Zombies gain more health (HP), and special zombies spawn more frequently.
-
Player Commands:
-
/blind– Opens the building construction menu (for shelters, towers, etc.). -
/skills– Opens the skills and perks menu.
-
-
Enhanced Mechanics:
-
Communication Tower: Used to call in airdrops for supplies.
-
Water Tower: Collects rainwater for drinking or hygiene.
-
Survival Items: Utilize Zombie Bile, First Aid Kits, Bulletproof Vests, and more to endure.
-
Critical Underwater Fix & Configuration (Shot UnderWater v1.01)
A key part of this mod is the included Shot UnderWater plugin, which is essential for maps with water areas.
What it Solves: By default, many weapons in CS 1.6 cannot fire underwater (e.g., XM1014, Galil, FAMAS, M3). This plugin allows full control over this behavior.
Key Features of the Plugin:
-
Configurable Per Weapon: You can specify exactly which weapons can or cannot shoot underwater.
-
Per-Map Configuration: Create specific rules for individual maps (e.g.,
fy_pool.ini). -
Seamless Integration: Works identically to the original game's mechanism, avoiding visual or audio bugs.
-
Efficient: Lightweight code with minimal impact on server performance.
How it Works:
-
The plugin uses a simple .ini configuration file.
-
A value of
1allows the weapon to fire underwater;0disables it. -
A default file (
shot_underwater.ini) governs all maps unless a specific map file is created.
Example Config Line:
ak47 1 # AK-47 CAN fire underwater m3 0 # M3 shotgun CANNOT fire underwater
Requirement: This plugin needs AMX Mod X v1.9 or newer to run, which is a standard requirement for most CS 1.6 mods.
Customization & Flexibility
-
Weapons: Add custom weapons by modifying the mod's source files.
-
Maps: Fully supports custom maps. By editing the provided INI files (which define supply points and zombie spawn coordinates), you can port the mod to any map.
-
Gameplay Rules: Fine-tune weapon behavior (like underwater firing) via the included plugin's configuration files.
Summary & Notes
This mod package delivers a complete survival experience by combining:
-
The main Zombie Shelter gameplay mod with building, skills, and survival mechanics.
-
The essential Shot UnderWater plugin, which fixes a major engine limitation and allows for tailored gameplay on aquatic maps.
Support: If you encounter bugs or issues, the author requests feedback to be passed on to the original developer for fixes.
In essence, this is a polished, feature-rich, and highly customizable survival mod that successfully brings a popular CSO mode to CS 1.6 while thoughtfully addressing technical constraints.
