Probably the most exciting part of the trailer is that it all but confirms multiplayer which was probably the biggest missing element of the first game.
Sure - the story is built around 4 characters - 4 teens, basically miniaturized to an ant's size, must navigate a backyard filled with dangers, craft tools, and find a way to return to normal size.
The multiplayer element is integrated by allowing up to four players to team up and work together in real-time to explore, fight enemies, and complete story objectives, fostering cooperation in survival and discovery.
When you connect to the game you select one of the 4 teens as your avatar - only esthetics and voice impact, no material change - and the game is well balanced so it's feasible whether you're 1, 2, 3 or 4 players joining...
The description and comments on the video 100% confirm multiplayer. Honestly I'd be excited for the game either way, but I have a lot of fun playing crafting/survival games with friends so it's appreciated.
