Much like their playthrough of the original, 11 Drunk Guys play Slender: The Arrival is full of funny moments. Special mention goes to them constantly running smack dab into the Slender Man, which, due to his height in game, makes it look like they're being T-bagged (which they continuosly lampshade) and their reaction to meeting Slendy's proxy for the first time.
If you turn on the debug mode and repeatedly enter "iamallama", the game will get mad at you and respond with increasingly hostile messages, culminating in locking the cheat codes for you to use.
"No you aren't"
"No you aren't, stop lying"
"Clearly you aren't, you're typing 'iamallama' and that requires fingers"
"I'm going to make Slender's Al harder now, just to spite you"
"Okay, maybe I won't this time, but next patch, I definitely will"
"I'm going to laugh up here from the console the next time you die"
I've had enough of this, good luck trying to enter your precious cheat codes"
From that point on, if you try to turn it back on the game responds with "hahaha...who's a llama now?"
When going through the caves in chapter 8 and reading all the graffiti scrawled on them, people with the texture quality at its maximum can make out one of the smaller bits of texts saying "don't give him 20 dollars," referencing a (at one time) popular joke relating to Slenderman.
