The “Be Nice” achievement requires players to share any food or drink with another player in The Forest. Players can only get this achievement in multiplayer mode with another player present.
To share any food or drink, a player needs to go to their inventory and combine the metal tray with the item they want to share. After combining, they must equip the metal tray and let another player interact with the equipped tray.
The achievement will pop after the other player acquires the food or drink.
