PSN MotorStorm-ed by Sigma add-ons

September began with a deluge of content being loaded onto Sony's PlayStation Network. In addition to five demos, the first week of the month saw add-on packs for MotorStorm and Ninja Gaiden Sigma. Though understandably not as robust, some further additions are coming to end September in much the same way, with add-ons for Ninja Gaiden redux part deux and Phil Harrison's most favorite racer, as well as a pair of demos landing on the PlayStation Network this week.

Tecmo has released its second of three planned add-ons for Ninja Gaiden Sigma. Whereas the Weapon Master add-on tasked players with surviving using a limited set of weapons, the new Speed Master download puts players under a time- and power-gauge limit in five survival modes. As with the first, the mode includes leaderboards and is available for $2.99. Fans of Sony Europe's off-road racer MotorStorm now have the Castro Capitano racing truck to cake with mud. As with the four rides released earlier this month, the Castro Capitano costs $0.99 to download.

As reported earlier this week, a trial of Clive Barker's supernatural spooker has been added to the PSN. In the demo, players will attempt to survive in the city of Al-Khali during the Crusades. As the spirit of deceased squad leader Cpt. Devin Ross, players are able to possess the bodies of heavy-weapons expert Sgt. Frank Delgado, telekinetic sniper Lt. Abigail Black, and enchantress and martial weapons specialist Sgt. Billie Church. Published by Codemasters, Clive Barker's Jericho is rated M for Mature, and is slated to hit retail on October 23.

The latest in the NBA circuit to take the court, NBA 2K8 from 2K Sports also has a sampler now available. Players can check out 2K8's new moves in a four-minute exhibition match. NBA 2K8 officially squares off against EA Sports' NBA Live 08 on October 2, a week after Sony's own b-baller, NBA 08, jumped into the retail game.
