I've been playing this mission for the past 5 years, and I remember playing something similar in the years before that, stretching all the way back to Arma 2 (not sure if it was yours).
To this day, I have yet to actually complete it. I always play on super expert (1st person lock, expert AI, no HUD, etc...), and with at least 4 of my friends. We've gotten extremely close sometimes. But the day we beat it we'll have a big celebration or something lol.
There is just something about this scenario that allows it to act as a timeless classic to me and my friends. We've joked about making a standalone game around this concept (similar to PUBG's start), but I think the base game of Arma 3 allows it to reach the heights that it does.
I'm surprised that you are still here pumping out updates for this. I guess it's for people like me who enjoy the challenge, but still, it is nice to see.
Do you have any other plans for this concept? My friends and I dream of a day where we can play it with more than 15fps. That'll be the day, lol.
