VERSION 2.1

• Integration of some features from the amazing gamemode "Map Sweepers"!
  
  • Added NPC SWEPs from "Map Sweepers". Huge thanks to the "Octantis Addons" team for giving me written permission to use their code all credit goes to them <3
• Added new Special Units for both Combine and Rebels, including:
  
  • Suppressor: A heavy support unit equipped with an M249 machine gun and a deployable plasma shield to protect themselves and their allies.
    
  • Wallhammer (Combine-exclusive): A heavy assault unit armed with a deadly short-range plasma shotgun and an indestructible deployable plasma shield. When the shield is active, staring at the Wallhammer for too long will blind the player. Unlike the Suppressor’s shield, the Wallhammer’s is indestructible and can blind, but it has a limited uptime and a cooldown.
    
  • Sniper: A long-range support unit equipped with a plasma sniper rifle. They prefer elevated, distant positions where they can safely pick off enemies with precision.
    
  • Medic (Combine-exclusive): A support unit that actively seeks nearby allies to heal a percentage of their max health, even during combat.
    
  • Engineer (Combine-exclusive): A crucial support unit for maintaining and defending important areas within a Combine squad. They can deploy two types of devices: a defensive turret and a regeneration device to heal nearby allies. Both devices have a limited lifespan, and the Engineer can only maintain one of each type at a time.

• Added episodic behavior support for NPCs (disabled by default on all Garry’s Mod maps except the Half-Life 2 Episodes). Some new behaviors available when re-enabled include:
  
  • Dynamic interactions: Certain NPCs can perform “executions” on others. For example: Alyx dodging Headcrab Zombie attacks, Vortigaunts executing Antlions/Headcrab Zombies, or Hunters executing Rebels.
    
  • Improved Antlion Worker AI: Previously, Antlion Workers would remain static during combat in Garry’s Mod unless forced by scripts. With this change, they now move much more dynamically during fights and can even climb elevated spots to spit acid from above.

• Fixes and adjustments to various parts of the code.
  
• Citizens/Rebels can now use the Weapon Switching feature.
  
• Rebels will no longer spawn with the following weapons: weapon_pistol, weapon_rpg. These weapons were harming their combat performance.
  
• Combine Soldiers and Rebels can now render a pistol holster on their side if their secondary weapon is a "weapon_pistol" (HL2’s default pistol).
  
• Added a popup warning for maps without a navmesh (can be disabled in the addon options).
  
• Added visual and audio feedback for the NPC armor system.
  
• The second weapon dropped by an NPC using Weapon Switching will now disappear after 1 minute (for cleanup).
  
• Fixed an issue that prevented Headcrab Zombies from triggering the “Faster Zombies” feature.
  
• Fixed a bug that caused some npc_combine_s to frequently T-pose in the "Map Sweepers" gamemode.

• Multiple performance optimizations implemented
  
• Numerous general tweaks and refinements

• Several functions have been reworked or replaced
  
  • Movement-related logic now utilizes the map's NavMesh to determine smarter destination points.
    
  • A bunch of changes to various features including some fixes.
• Weapon Switching:
