BEAT THE RUSH (No mods/maps or downpatch required)

Get the broken achievement BEAT THE RUSH with no mods, custom maps or downpatching the game.

Introduction

Based on WaifuRuns recently information (Here), BEAT THE RUSH achievement is totally broken and impossible to achieve in a legit way with the current patch of the game, only because the requisites to trigger it is not tied to your character only, but also to all players, bots and creatures in the map.

Quick overview

With this information in mind, the only way I found to trigger this one was cheesing with the console to kick everyone for four minutes, and, for my surprise, it works.

• Enable Console access in Options Menu.
  
• Kick all bots by using the "kick" keyword.
  
• Repeatedly kick all specials with the "kick" keyword before they reach you.

Setup

First, see in the achievement list what map you don't have bronze medals. The bronze medal needs only 4 minutes to achieve and will be easier to trigger.

Select the map and when it starts, immediately enable the console to use the "kick" keyword and kick all Bots.

Playing as Bill use:

 kick zoey; kick francis; kick louis 

Now on the same screen, bind the command to kick all special monsters in the "v" key.

 bind "v" "kick smoker; kick jockey; kick charger; kick hunter; kick spitter; kick boomer; kick tank; kick (1)smoker; kick (1)charger; kick (1)jockey; kick (1)tank; kick (1)hunter; kick (1)spitter; kick (1)boomer kick; (2)hunter; kick (2)smoker 

Command provided by Humjob, Texas Ranger on:
ACHIEVEMENT GUIDE 100%, LEFT 4 DEAD 2 ALL 101 ACHIEVEMENTS

Playing

If everything is correct, grab any melee weapon on the map, activate the horde, hide in some place where the specials need some work to find you and mash the "v" key for 4 minutes while you kill all zombies.

• Apply all commands and kick all bots as soon as possible.
  
• Don't let any special use any skill on you, kick everything before they even walk near you.
  
• Try to stay in some corner or place where you can funnel the zombies in front of you and kill them with melee while you mash the "v" key.
  
• Don't use any item besides the melee weapon.

Conclusion

I finally manage to get this achievement on the same day I wrote this guide for you.
Thanks to WaifuRuns for providing the knowledge to work around and I hope you reader finally unlock this one as well.
