Since it took me a week to come up with my idea, this will basically be a one-week challenge, but who's counting? I don't really play a ton of video games, so my knowledge of them is basically middle-aged-'80s-dad level at this point. Plus, when I make customs, I usually try to make sure they'll have a place among one of the projects I'm already working on. But it took me six days to remember that there is one video-game-based figure I've been meaning to make for a long time now, from a video game I've barely even played and didn't enjoy that much when I did:

Dutch from Alien vs. Predator!
The game was boring as hell, but I loved that Dutch made a triumphant return, with a giant robot arm that only makes him cooler. I've been circling the idea of making a custom of that design for years now, and what better excuse will I have than this CC?
Now it's just a question of whether a certain part will arrive in time. I laid out a rough idea of the parts, and ordered a figure that should complete it. A trip to storage to dig into a box of junk for one more piece and I should have a mock-up ready by tomorrow night.
