If the player already has a single upper-body or lower-body restraint equipped and then equips a full-body restraint, it overrides the existing one. But in the original game, if an upper-body restraint is present it stays, and the full-body restraint only covers the lower half — so you'd end up crawling around with astonishing core strength. Arguably more variety, but way too illogical. By the way, the game supports six languages: English, Japanese, Korean, Russian, Simplified Chinese, and Traditional Chinese.
