I can't recommend this enough.

If you have any kind of love for the Terminator franchise and older less-ESG'esque games, this is a fun experience.

Does it feel dated? Yes, at some times it does. This isn't a AAA experience, but I'd say it would've easily been AAA if it came out in 2013/2014.
The story is interesting and there are enough optional choices to make your experience seem like it carries weight.

The combat is difficult at first and the T800s are scary at first but once you get to use SkyNet's power against them, they're a challenge that can be beaten.
I finished the game on Hard, so my experience was likely not what intended, but I found it challenging but fair.
The only time I actually felt annoyed was in the Hollywood Hills segment.
Beyond that? Absolutely adored this game.

Infiltrator Mode:

A mode that comes with the base game where you play as a Terminator and wipe out an area of scavengers and resistance soldiers as you go after a single target. A lot of the gameplay would later make its way into RoboCop, so it's pretty cool to see. You also get a few guns I didn't find in the main game, like the Minigun - which makes sense.

A fun, but brief experience that gives you a score at the end.
