Quick answers

Is Platypus co-op?
Steam's store page doesn't flag a co-op category, but players tag Platypus as co-op.
Does Platypus have PvP?
Steam does not list PvP for Platypus.
Do we both need to own Platypus to play together?
Not always. Platypus supports Steam Remote Play Together: one person who owns it hosts and streams a local session to friends who don't (Steam quotes up to four players, more on a fast connection). For online co-op or PvP, every player needs their own copy.
How many people play Platypus?
About 2 players were in-game when this page's data was last refreshed (2026-09-09).
Does Platypus have split-screen or local multiplayer?
Yes. Steam lists Platypus with shared/split-screen play on one PC — and it supports Remote Play Together, so a friend can join that local session over the internet.
