Deep in the heart of the Las Vegas desert the real Lake Mead is "alive and well" with water skiers and jet skiers. The virtual Lake Mead found in Fallen Earth won't be ready for prime time when the game goes live, but will come online through a later expansion. However, it too will be accessible via the Hoover Dam. Just like in real life.
The Sneak/Stealth skill is made up of both active and passive parts. The "I heard something" part is passive, while the "I think you're an enemy faction member in disguise!" part is active and requires a player to activate an ability on the target. Hopefully, this MMO won't sneak past the gaming populace when it drops because the more we learn about it the better it sounds.
