⚠ Left 4 Dead 2 - Rare "Good Guy Nick" Achievement

Seems like the Left 4 Dead 2 free weekend is back again for the "Steam Spring Cleaning" event, which may be an annual event now, making the achievement more accessible. As far as I know it's the only Left 4 Dead 2 free weekend event and so the only time you can get this achievement legitimately. Be aware that it is fairly difficult to find free weekend players.

Original Message from 2018:

This is the first time since 4 year that you can get this achievement, it requires you to finish a campaign with a free weekend player (who has to survive the campaign). Free weekends haven't happened for 4 years, until now with the "Steam Spring Cleaning" event you can finally unlock it in the next 2 days. I highly recommend you get this achievement now if you own the game since it's unlikely you'll get another opportunity soon (if ever). The achievement doesn't unlocks for the free weekend player unless there's another free weekend player in your group.

Completing one of the shorter campaigns takes around 15 to 30 minutes on easy difficulty. "Crash Course" is the quickest campaign to complete, though some might prefer "The Sacrifice". The game is actually kind of fun, though it gets repetitive after a while. The main gameplay is moving from point A to B while killing (First Person Shooter style) endless re-spawning zombies, and sometimes defending a point for a while.

Edit: I got the achievement, but if anyone needs help just let me know. I'm not a free weekend player myself though since I own the game.

It's possible to obtain the achievement alone if you play with your main account (it has to own the game) and an alt account (it must not own the game) at the same time (2 PCs side by side). Playing like this is harder but you can get it.'

I suggest anyone who really wants it checks the discussions frequently, lots of Good Guy Nick helpers around there, but ofc there's also a lot of people in queue wanting to get it.
