At E3 2018, I went hands-on with a portion of a brand new level being added to all versions of the Crash Bandicoot N Sane Trilogy: Future Tense. Future Tense is accessed in Crash Warped via a floating platform in the hub and is available from the very beginning of the game. It’s a completely original, futuristic level featuring some familiar hazards that have been molded or reimagined to form far more difficult challenges. The level takes place in a chrome, futuristic setting, but it includes some redesigned ideas from the cut Waterfall level, such as water wheels. You won’t see any actual Waterfalls, but you may see some nods to the cut hazards!
Future Tense is completable at any point in Crash Warped, but all the collectibles cannot be gotten until you’ve unlocked some other abilities by playing through the game. So you can try it right away when you pick up Crash, since the level is free and included with the game.
