Rockstar Games is rumored to finally release a new downloadable content that will feature Zombies in addition to the highly publicized Online Heists DLC that is expected to come to 'GTA Online' and 'GTA 5' this year.

According to Youtube video host Chr0m3xMoDz, he claims that the Zombies DLC is confirmed and it will be in available in single player mode after he revealed the leaked source code in one of his online videos recently.

In other 'GT5 Online' news, YouTuber iCrazyTeddy recently revealed new information regarding VIP Missions in the popular game.

"Escort a VIP's car to a random landmark in the city then back to their hotel. Cops escort the car as they see the sights. Criminals are given the tour points and look out for the VIP. If driver dies, cops can drive and resume the tour. Criminals can get in the car at any point and drive VIP back to gang house for extra rewards. VIP is taken from a hotel (from list of 8) to an important place in town (list of 8). Make sure the start and end points are far enough away to give the crooks time to play properly. Unlocked at Rank 4. 2 cops and 6 criminals can join mission. Shoot to kill," according to the Youtube video.

Rockstar Games released the popular game 'GTA 5' on the PS3 and Xbox 360 in US stores on September 17, 2013; while 'GTA Online' was released on October 1, 2013.

The newest port of 'GTA 5' will arrive in stores for the PC, PS4 and Xbox One in Fall 2014.
