Ratchet and Clank: Rift Apart is now available on PC, which means that developer Insomniac's claims that the game was only possible with the power of the PS5's SSD are being put to the test. Turns out that the developers were right.

Our first look at Ratchet on PC! It has a few issues but it's overall in good shape! Infinitely better than TLOUP1 and Jedi Survivor at launch.
