The gameplay of Chains of Olympus is similar to its predecessors; it is a third-person action adventure game that focuses on boss fights. Also familiar to the series are box-based puzzles and the quick time events . There are fewer tightrope walking sequences in the game that were prominent in previous games of the series.

Kratos still collects red orbs to power up his weapons and abilities. He also collects Gorgon eyes to increase his health and Phoenix feathers to increase his magic. The game's controls remain mostly unchanged but because of the PSP's reduced amount of buttons the game uses both shoulder buttons and the analog stick in order to dodge.

God of War's weapons include Kratos's trademark Blades of Chaos, the weapon that was given to Kratos by Ares when Kratos agreed to serve him and the Gauntlet of Zeus, a magical gauntlet that allows Kratos to unleash devastating punches on his opponents. There is also a Sun Shield that Kratos picks up that allows him to block most attacks, parry an attack that stuns the opponent and also deflect projectiles back at enemies. Kratos also acquires magical spells throughout the game that helps him deal with the amount of enemies he faces. This includes the Efreet spell, which knocks out all nearby enemies, the Light of Dawn, which allows the player to throw balls of light, and Charon's Wrath, which can inflict damage on several enemies. There are three major bosses in the game: the basilisk, Charon and Persephone, as well as a shorter mini-boss fight with a Persian king.

There's no sense in beating around the bush -- Resistance: Retribution is excellent. It's got a main character you'll connect with, an engaging single-player campaign, a crapload of unlockables, PS3 connectivity and the strongest online multiplayer I have ever seen in a PSP game. In short, you're an idiot if you don't buy this game.

Set between Resistance: Fall of Man and Resistance 2, Retribution tells the tale of James Grayson. A British Marine, Grayson was doing his part in the fight against the Chimera when he and a pair of soldiers stumbled into the middle of the Chimera conversion process (i.e. a beast turning a human into a monster). The boys took out the overseeing baddie but discovered that the person on his way to becoming the enemy was actually Grayson's brother. Grayson kills his own brother and it basically cripples Grayson's life as he knows it. He goes AWOL from the armed services and sets out on a one-man campaign to blow up every conversion center he can find. After eliminating more than 25 of the enemy bases, the Marines catch up to Grayson. See, while he's become a folk hero to the human race, the Brits aren't too keen on desertion; they arrest, try and sentence Grayson to death. Before he can face the firing squad, the European resistance known as the Maquis pops up to ask for some help delivering a serum that should clear out the Chimera. The Brits agree, release Grayson and the war is back on.

Imagine that someone told you one of the best games on the PSP didn't have a well-known franchise character, gameplay that pushed the tech of the system or was a port of a PS2 title. You might not believe them, but almost two and a half years ago, Sony introduced LocoRoco, a unique puzzler that was engaging and addictive. Well, after a brief hiatus, the sequel to the award winning game will be released next week and it reunites the same group of lovable characters with a new adventure. Coming with a new bag of tricks for players to check out, LocoRoco 2 improves on most elements of the first title, with the lone exception being the brevity of the main adventure.

The story of LocoRoco 2 takes place where the first game left off, with the Moja sent running back to their own planet in defeat. However, Bonmucho, the Moja's leader refused to concede to the cheerful blobs and their planet, and has planned a brand new attack upon the LocoRoco world with a powerful new musical weapon -- one that drains the life and color out of anything that hears its notes while covering them in darkness. Trying to gain revenge on the LocoRoco, the Moja quickly return to the blob's homeworld and attempt to conquer the planet with their dark songs. Even worse, the Moja have recruited the Bui Bui, the evil counterparts of the Mui Mui (the LocoRoco's friends) to help attack the indigenous creates. It's up to the squishy blobs to gather their friends together and try to free their world once again. In some ways, it feels a bit similar to the first title, but there are a couple of gameplay twists that help to keep the story fresh.
