Subnautica 1 · Legacy Arcade
Sub 2 hasn't shipped yet, so the arcade pulls from the original Subnautica's 42-creature catalogue. Sub 2 versions land when the new roster drops.
Endless · Black outline
Endless survival mode. Name each Subnautica 1 creature from its black silhouette alone. One wrong guess ends your run. Peeper to leviathans.
Endless · HP showdown
Higher or lower? Predict if the next Sub 1 creature has more or less HP than the one on screen. Reginald (~50 HP) to Sea Dragon (10000 HP). Equal HP always counts.
Daily · Coming with launch
Sub 2 versions of every game land here once Unknown Worlds reveals the new creature roster. Until then, the Sub 1 games above keep the lights on.
