Disregard the last persons response it is possible to mod the 360 version of GTA 4 but the problem is having the time to find the mod. The site I used was closed but there are many Mods for GTA including but not limited to Zombie, Raptors(Dinosaur), and Car.
You must complete the achievement "let Sleeping Rockstars Lie" To do this you must kill one of the rockstar programmers that worked on GTA 4 while playing online
There isn't an intentional zombie mode in Grand Theft Auto 4, but you may have a group of people dress up as the zombie model and play Survivor.
yes you can play up to 4 players in nazi zombies.
you can play 4 player on zombies (black ops) but not offline you must play only nazi zombies i just found out sorry :)
Halo, GTA 3, Super Mario, Plants Vs. Zombies

Yes, you need to pay to play online on play station 4 Examples GTA Online The Crew
