≈ $10/mo
playing ~12 h/week on the metered plan, billed only while the server is actually up. Always-on is $29.99–$59.98/mo · about $7.50 each split between 4 players, 1–2 cores dedicated, never shared.
Very light 2D sim — runs on modest hardware; late-campaign saves creep RAM.
Get the game
You buy Barotrauma once from Steam. It is $19.99 there, a one-off purchase. NecroHost rents you the server it runs on, which is the monthly figure above.
