Its basically like he's almost entirely unimmersed in the game. He makes dumb jokes as usual, makes dumb jokes when there is music and just doesn't seem to really look like he cares about the game (although he's said he's having fun so far).
It's a typical Phil behavior, he breaks down every game he plays in its mechanical aspects and ignores the world building and storyline like they don't exist in the game or are just a nice but unnecessary addition.
I remember how he walked through the sewers and had a burned corpse right in front of him, for seconds,he even pushed it. Not a single immersed word about it, just "Are there more health packs?" because his health was low.
Or as an NPC thanked for his help, he just gave a goat laugh instead of an "No problem sir, you're welcome. When this is over we should go bowling".
There was also this part where he drove through some pipes with his boat and said observational: through the pipes.
And I said: And now you will repeat yourself.
And Phil repeated himself.
For someone who always claims he creates entertaining khantent (something you should never claim about your own videos) this was, as usual, quite the opposite.
He fails hard as an entertainer.
So based upon what he's saying.
The last time he played this game he got to where you get the gravity gun...
and quit the game?
That doesn't even make any sense.
Funny. He also said he never played the game right after the boat gameplay.
