The long-dormant rocket launcher plugin has finally found a new model! This time, it's the M4 Gustav recoilless rifle from COD20. Unlike the RPG-7's direct fire, the biggest feature of this mod and its supporting plugin is the ability to fire guided projectiles! They can turn corners, so enemies can't escape now!

The Gustav recoilless rifle model comes from the recoilless rifle mod for L4D2, originally created by Animal33 and published by 无名氏の小窝. We have obtained permission from both. I ported it to CS:S and perfected the scoping-in animation, while Old Jesse added the sprint animation. This weapon now supports manual inspect, dynamic scope effect (requires ADS plugin, triggered by right mouse button), and sprinting (requires Running with weapons plugin, triggered by holding Shift+W). Special thanks to all the masters mentioned above!

The supporting plugin is a new one I modified based on the old rocket launcher plugin. It should not conflict with the old RPG-7 plugin that replaces grenades or flashbangs.

The Gustav recoilless rifle mod fires guided projectiles using manual command guidance.
This means that after firing the shell, the player must continuously keep the crosshair or the red dot of the scope (when aiming down sights) aligned on the target until the projectile hits and explodes (★ Just keep holding down the left mouse button after the shell is fired).
Even if the target moves quickly, the projectile's trajectory can be adjusted accordingly (it can even turn corners!) until it hits a solid surface, ensuring it ultimately strikes the enemy!


Important Notes:

1. This mod has three versions: one replacing the p228, one replacing the desert eagle, and one adding it as a new weapon (parent class is desert eagle). Players can only choose one to download and use!

2. This mod requires Plugin platform version 1.08 or higher. The "add as new weapon" version additionally requires the adding new guns plugin.

3. The desert eagle replacement version might conflict with the RPG-7 mod that also replace the desert eagle, although I have never publicly released the latter.
