Yes there are actual Terminator 2 games, most of them (arcade gun game excepted) garbage. This, sadly, is not one of them. Instead, it makes use of mods to turn Grand Theft Auto: San Andreas into...machinima? Art? Either way, it's one long love letter to James Cameron's 1991 classic.
This was actually released last year, and nobody really noticed. Shame. Because it's amazing. So thanks for digging it up, shuri!
WARNING: The weird butt textures on the Arnie model at the start of the first vid may be unsettling to some humans.
Unfortunately, that's as far as the creator got, so there's no poorly-modelled thumb sticking out from a low-res pool of lava.
