A free trial of Battlefield 4 will be available tomorrow on the PlayStation 3 for PlayStation Plus members.

"The free trial version contains the full Battlefield 4 base game and will be available for 20 playable hours from the first moment you start playing. To download, simply head to PlayStation Store, search for Battlefield 4, and locate the trial version," Sony posted on the PlayStation blog.

DICE is offering the game for free to entice players to give the game one more chance as it has been plagued with problems for the last six months since its release.

Battlefield 4's upcoming Dragon's Teeth DLC, had some gameplay features and pictures leaked through online hackers who accessed coding in the files.
GameSpot reported, users on Reddit and Symthic searched through files, and unlocked new weapons in the PC files of the game. The guns found include: Desert Eagle, Unica 6 Magnum, SIG MPX, SRSS Bulldog 762, and McMillan CS5. There was also a ballistic shield and a remote control robot fit with a machine gun and rocket launcher. The shield had previously been confirmed by DICE, but never seen.

GameSpot also reported the rank cap may raise from 120 to 10. The DLC will include four new maps as well, Marketplace, Propaganda, Urban Garden, and Waterfront.
Dragon's Teeth is expected out this summer although DICE has not revealed the actual date yet.
