PS4 games are now available for pre-order through PS3 on the PlayStation Network.

According to a promo screen for the PlayStation Store, gamers can now pre-order Knack, Killzone: Shadow Fall, Battlefield 4, Assassin's Creed : Black Flag, Warframe, and Call of Duty: Ghosts

"Today we're rolling out more PS4 game pre-orders on PlayStation Store. Last week, we made Knack and Warframe available for pre-order, and today we're releasing pre-orders for Killzone Shadow Fall, Call of Duty: Ghosts, Assassin's Creed IV Black Flag, and Battlefield 4," the

PlayStation blog said on their site.

They continued, "If you pre-order these titles today, you'll have them when they launch for PS4. As an added bonus, all four games feature exclusive pre-order bonuses."

The games and their bonuses are as follows:

Killzone Shadow Fall "The Shadow Pack," Call of Duty: Ghosts "Free Fall Map," Call of Duty: Ghosts Digital Hardened Edition "Free Fall Map," Assassin's Creed IV Black Flag "Exclusive Aveline Figurehead," Assassin's Creed IV Black Flag Gold Edition "Exclusive Aveline Figurehead," and Battlefield 4 "China Rising Expansion."

Sony is also allowing people who have pre-ordered games for the PS3 that are also coming out for the PS4, an option to upgrade for $10.

This will only be a limited time offer reports Gamespot.

Sony recently announced last week that two Playstation 4 launch titles, Watch Dogs and DriveClub, are being dropped from release day because they will not be ready in time.

Watch Dogs and DriveClub were originally part of PS4 launch bundles, but will now be kicked back to at least April.

According Mirror, Amazon and Gamestop said gamers will still receive their launch day consoles, but it is unclear whether they will receive money back for the game or just a delayed pick up.

The Playstation 4 is set to release on November 15 in the U.S., and on November 29 in the U.K.
