Major Update 1.0.4.0

HIGHLIGHTS:

- Perk System: Each class now comes with a full set of unique perks. Perks are unlocked as waves progress and can lead to significantly different playstyles. Class perks can also be configured in the class config menu. To create a perk on your own, see here: https://github.com/tpan496/Horde/wiki/Creating-Custom-Perks

- New Class: Berserker. Berserker is your typical melee character that can be played both offensively and defensively.

- Class Config Rework: Class config now comes with more customization options (e.g. class name, icons, models, perks, etc.)

- Mutation: In the eneny config, you can now grant enemies with additional mutations. Mutated monsters have special particle effects. Mutations can be added in similar ways as Perks. Horde comes with several default mutations:
- Fume: Enemies are surrounded by a Poisonous aura.
- Shielding: Enemies have a regenerable shield that regenerates if they are not taking damage.
- Nemesis: Enemies explode on death, dealing a portion of their health as damage.
- Frenzy: Enemies have increased action speed.
- Regenerator: Enemies slowly regenerates health.

Random mutations appear only on Realism/Nightmare. To create a mutation, see here: https://github.com/tpan496/Horde/wiki/Creating-Custom-Mutations

- New Difficulty: NIGHTMARE difficulty. On Nightmare diffculty, enemies have similar stats as in Realism. However, enemies have a much higher chance to spawn with a random Mutation.

- Starter weapons: Players now always spawn with a Crowbar and 9mm pistol.



DEVELOPERS:

- Damage System: Horde now uses a more in-depth damage system. If you want to create custom perks, it is recommended that you see here first: https://github.com/tpan496/Horde/wiki/Damage-System

- Healing System: Since GMOD does not have its own healing hooks, Horde now uses its own healing hooks, which you should be using as well if you want healing from other addons to work with Horde (e.g. medic buffs). See https://github.com/tpan496/Horde/wiki/Healing-System



DEFAULT CONFIG GAMEPLAY UPDATE:

- New weapons: RPG-7 (Demolition), Katana (Berserker), Bat (Berserker), Barret AMR (Ghost), AWP (Reworked, Ghost), MP5K
- New enemies: Burnzie -> Scorcher and Crabless Poison Zombies -> Vomitter are now ranged enemies. Scorcher deals FIRE damage, while Vomitter deals POSION damage.

IMPORTANT NEW COMMANDS:

- horde_enable_perk(0/1) - Enables perks or not. Default is 1.
- horde_perk_start_wave(0-10) - First wave where Tier 1 perks will be unlocked. e.g. At 1, then Tier 1 perks are unlocked after Wave 1.
- horde_perk_scaling(0-) - The multiplier to the level for which wave it is unlocked. This does not affect Tier 1 perks.
e.g.
At 2, Tier 2 perks are unlocked after (start_wave + 2 * 1). Tier 3 perks are unlocked after (start_wave + 2 * 2).
At 3, Tier 2 perks are unlocked after (start_wave + 3 * 1). Tier 3 perks are unlocked after (start_wave + 3 * 2).
- horde_free_perks - This command sets start_wave and scaling to be both 0.
- horde_testing_unlimited_class_change - Allows for unlimited class changes during break. Please use this only for testing purposes. I will not fix any problems that might be caused by this.
- horde_enable_starter(0/1) - Give player starter weapons or not.

- AR2 removed from default config since it two-shots everything.
