PlayStation Store Update: Mass Effect 2 Arrival DLC, Free Realms

It's a bustling week on the PlayStation Network as new content, including the latest add-on pack for Mass Effect 2, is now available alongside a slew of other PS3 and PSP games.

Leading the pack this week is the Arrival ($7) content for BioWare's critically lauded sci-fi role-playing game. Arrival sees Commander Shepard investigating clues to an impending Reaper invasion on the edge of the galaxy. The downloadable content will also see the return of actor Lance Henriksen (Aliens, Stone Cold) lending his voice to Admiral Hackett.

The latest add-on for Mass Effect 2 has arrived.

Being released on the PS3 today after more than a year as a PC exclusive is Sony Online Entertainment's Free Realms (free). Aimed at the family-friendly set, the game is a massively multiplayer online role-playing game where combat is optional. It includes an assortment of quests, minigames, themed events, and social-networking features, including the ability to upload in-game videos to YouTube.

Also out now for the PS3 is Rush 'N Attack: Ex Patriot ($10). In the game, players will control a lone soldier sent into Russia to find a missing ally, equipped with nothing more than a knife. As in the original, different weapons can be picked up from dispatched enemies, but the game will also include a stealth mechanic to mix up the old formula.

Gamers looking to grab a title from yesteryear can download Sonic the Hedgehog ($5) today for the PS3. The original Sonic game has players zooming through colorful zones and rescuing animal friends from the nefarious Dr. Eggman.

Staying with the time-traveling trend, Sony has added the second episode in the Back to the Future: The Game series to the storefront. Titled Get Tannen (free with season pass), this latest chapter in the saga sees players controlling Marty McFly and tasks them with stopping Kid Tannen from meddling with McFly's family and forever changing the future.

Other new games out for the PS3 are futuristic side-scrolling action game Moon Diver ($15), Disney's racing game Split/Second ($30), and musical block puzzle game Chime Super Deluxe ($10).

Switching to the PSP download space, Sony added four new games to the spot this week, the first of which is WWE All Stars ($30). The arcade-style wrestling game has players fighting in between the ropes as any of many classic fighters, including Hulk Hogan and "Macho Man" Randy Savage.

Also out now for the PSP is The 3rd Birthday ($30). The game stars Parasite Eve franchise protagonist Aya Brea, who once again is put in the position of saving humankind from a monstrous biological menace. Set in Manhattan in 2012, the game sees the city beset by the monstrous creatures known as the Twisted, and Aya is once again tasked with saving the day.

The last two games out for the PSP now are Don Bluth's arcade game Dragon's Lair ($8) and the role-playing game Legend of Heroes: Trails in the Sky ($30).

A full list of the week's deals and new PlayStation Store content, including themes, wallpapers, demos, discounts, and add-on content, is available on the PlayStation Blog.
