Easy way to get "Test complete" achievement

This is quite a hard achievement to get, as it requires you to complete a series of missions in which you have to defend against a number of waves of enemies. However there is a glitch that enables you to get the achievement in about a minute without even firing a bullet.

Here's how to do it

Load up the mission and enter the virtual reality combat simulator. Select any random weapons as you won't need them anyway and then proceed to start the first mission. As soon as the mission starts hold Tab for the weapon inventory and spam G for the gasmask. After a few seconds the guy will say that the mission is complete and you will return to the mission hub area. Repeat the process for the remaining missions which will take a minute or so.

Any guide is there to work on complete edition??

It sucks this glitch only works on redux not complete edition.

This is a bullshit glitch. LOL. I'm glad I discovered this glitch after finishing the TOWER level so I can improve my aiming.

just use S.A.M in other words Steam Achievement Manager and give it to yourself

Why does this cause the game to believe that the level is completed?

Thanks for this! Now I can skip what is objectively the worst part of the entire game AND still get 100%.

Baffling to see people get so mad at this. Is achievement hunting really so crazy a concept to them?
