Grounded: Hot and Hazy Update - New Gameplay Mechanics
Hot and Hazy adds several RPG elements to Grounded. Players can now upgrade their character's health, stamina, thirst burn rate, hunger burn rate and maximum active mutations. To do that, you'll need to collect Milk Molars, which can also buy increased resources, ammo, and food stacks.
Weapon stats can be improved using new Globs. Upgradeable via a Smithing Station, those come in three categories: Minty, Salty, and Spicy. Once used, that upgrades your weapon to the matching Glob type. Obisidian's also changing armour sets, now offering Light, Medium and Heavy armour.
Finally, there are several quality-of-life improvements coming too, such as new tutorials. A Brain Power system has been added to unlock crafting recipes, while further adjustments were made to visual effects and Grounded's accessibility options.

As for Grounded's locations, players can now explore the Black Ant Hill biome, which is hidden beneath the Sandbox biome and includes Grounded's first ever mini-boss. A lab area has been added here too, letting you harvest Black Ants for new equipment.
Elsewhere, there's two new landmarks called The Picnic Table and The Trash Heap, which both feature significant new items. Haze Biome's getting updated too, adding more incentive for players to visit with a new lab and infected insect variants.
