Survive, Collect, Craft, Trade with Players, and Perfect your Dream Build. Delve into dream worlds to face your past Visions from lingering nightmares stuck to the back of your brain. Collect over 350 Visions and possess them as your own friends to help you become more powerful as you jump from the Lucid World to the Dream World. Earn experience, loot, materials, and other unlocks that will stay with you permanently in the Lucid World. In your Dreams, gain new and powerful boons to temporarily help you erase any Visions in your way. In the Lucid World, craft new items and materials for use in your Dreams, or trade them with other players worldwide in the Bazaar. Create custom loadouts to tackle the variety of challenges that can be encountered in three activity modes with a range of difficulties. In Horde Runs, survive waves of Visions as they close in on your position. In Extraction Lairs, you will explore randomly generated dungeons filled with a healthy amount of plunder. To escape with all you've collected, you will need to find the exit and defeat the Final Vision. In Invasion Zones, a never-ending supply of Visions will rain down upon you relentlessly as you try to catch falling loot and duck danger. The Visions you encounter can be turned into your own personal pets called Casters, fighting besides you with their own stats, perks, and utility. If you cannot get the perfect god roll, craft your own with materials or browse the Bazaar for other players' listings. hellamental is free-to-play, has no ads, no Wi-Fi required, and no restrictions on the the amount of time you can play.
