SteamAbout DIEVER
■Into the Deep Sea
You wake up alone in a cramped space underwater, wearing a heavy diving suit.
They command, “If you want to live, aim for the depths.”
Is this a punishment for me, a sinner? Or is it a chance at freedom?

■ A Heavy, Restrictive, and Lonely Struggle
There are no flashy combos or graceful dodges.
You simply stand there, gauge the distance, punch, shoot, and endure. That’s the extent of the back-and-forth.
Keep an eye on your HP and remaining oxygen, and master this rugged battle.

■ Over 90 types of weapons and armor combined.
By building your character around base stats and special abilities based on rarity,
you can enjoy a different combination every time.

■ From Human to Something Else
Am I changing my gear, or am I changing my body?
The line between the two grows increasingly blurred the deeper I dive.
