The game also had support for mods. After the first playthrough I've always played the game with the kongfu mod enabling wallrunning, kicks, additional weapons such as Sticks, and various other action orientated changes.

Additionally, I believe Rockstar gave the go-ahead for work on a remake for 1 & 2. Hopefully they have James Perry McCaffrey's voice work in good enough quality. RIP.

I remember playing a matrix mod. It was awesome. There was this famous fight near stairs with so much bullet time and effects. Another was near an elevator with pillars.
