A time capsule is a boxful of objects from today's world, buried or otherwise hidden away so that people from the future can rediscover and understand current Hot Trends such as wearing mismatched socks or electing washed-up businessmen with fascist tendencies. Unless, that is, it's a time capsule in sci-fi ocean survival game Subnautica, in which case it contains: THE FUTURE. Developers Unknown Worlds have been sneaking pictures of the forthcoming Subnautica 2 into the original game's time capsules, offering glimpses of its flora and fauna.
