Ape Escape 3

Playing as either Satoru (Kei) or Sayaka (Yumi), gameplay follows that of the previous games in which the player must catch several monkeys by using various gadgets controlled with the right analogue stick. While there are fewer gadgets in this game than previous entries, a new feature in this game is the ability to morph into different forms through a device built by Aki. Some monkeys may also try to steal the player's Stun Club or Time Net and use it against them, and can even force them out of the level by catching them with their own net. Playing as Sayaka has an additional benefit; owing to her pop idol status, certain monkeys will go star-struck upon sight of Sayaka, allowing for an easy capture.

A minigame featured in the game is Mesal Gear Solid: Snake Escape (メサルギアソリッド, Mesaru Gia Soriddo), a spoof of Metal Gear Solid (the name is a pun on "metal" (メタル, metaru) and "monkey" (猿, saru)). In this game, players control Pipo Snake, a monkey loaded with Solid Snake's battle data, sent on a mission to rescue Snake and destroy a monkey-like Metal Gear. Gameplay is similar to Metal Gear Solid in which players have to use stealth and weapons to sneak around undetected and rescue prisoners. Players are equipped with a Banana Pistol for stunning enemies and Pineapple Grenades for breaking open flimsy walls.

Specter, the Pipo Monkeys' leader, finds a Monkey Helmet, and hires the human scientist Dr. Tomoki (Dr. トモウキ, Dokutā Tomōki) to aid him in his evil plans. They establish television stations protected by the Freaky Monkey Five where they plan to broadcast TV shows worldwide.

The television shows that are broadcast on every television put every human except the twins Satoru and Sayaka (Kei and Yumi in the North American English version), their aunt Aki, and Natsumi (Natalie) into a mindless trance. When Natsumi informs Satoru and Sayaka that Kakeru (Spike), Hikaru (Jimmy) and the Professor were all infected by the television show, Satoru and Sayaka go out to catch the monkeys and thwart Specter and Tomoki.

Ape Escape 3 received "generally favourable reviews" according to the review aggregation website Metacritic. In Japan, Famitsu gave it a score of 36 out of 40. GamePro said, "Ape Escape 3 runs smoothly and is worth your hard earned dollar. It's a fun, perfect time killer—especially for the obsessive gamer who likes to complete 100 percent of the game."
