Optional objectives invite you to spend longer at each planetary stop, from earning additional trophies in hoverboard races to collecting more Telepathopus brains in return for bonus kit. But by far the most persuasive reason to explore every nook of these lovingly redesigned worlds is the addition of collectible trading cards. These aren’t merely tucked away at the end of branches from the crucial path, but are coughed up by defeated foes; indeed, many weapon upgrades increase your chance of cards dropping. They come in themed sets of three, the completion of which gives you further buffs; to fill in the gaps in your collection, you can swap five duplicates for any card. An additional set of hardto-find variants unlocks the final gun, the powerful RYNO.
