While Ratchet & Clank: Rift Apart is exploring new worlds, it hasn't forgotten its past. The game appeared at the PS5 reveal showcase and was one of the few games to really highlight what PS5's architecture might mean for next-gen. The major focus of the Ratchet & Clank: Rift Apart trailer was the dimension-hopping gameplay and the new female Lombax character, but fans have spotted hints of classic characters.
First up is Captain Qwark, a major character in the Ratchet & Clank mythos. A ship in Qwark's colors appears at 1:12 in the official trailer, as noticed by R&C fans on Reddit. Quark was once a renowned hero in the galaxy, only to be revealed as a villain working with Chairman Drek, the primary antagonist of the first game. Qwark became the primary villain of the second game in the series Ratchet & Clank: Going Commando.
In that same section of the trailer, you can also see a news report by Dallas Wanamaker and Juanita Alvaro, a pair of reporters that first appeared in Ratchet: Deadlocked. Both were the commentators for DreadZone, the gladiatorial arena that Ratchet was forced to participate in.
Ratchet & Clank: Rift Apart uses the super-fast SSD storage on the PlayStation 5 to allows the duo to quickly and seamlessly switch between dimensions with no loading times. The trailer itself showed Ratchet switching between wholly different worlds, while the gameplay feature only showed transitions within the same level. Ratchet & Clank has eight games to draw history from, so it's possible that Rift Apart may visit the locales and characters from any of those titles. Currently it has no firm release date, but hopefully Ratchet & Clank: Rift Apart will come quickly after the PS5's Holiday 2020 launch.
