ArkumSMP is a community server running a competitive Duo Survival Games event on a hand made Desert Wasteland map. It does not use normal world generation so the whole place is built for fights and smart movement.
The gameplay is meant to feel like pure Survival Games with custom coded chest tables. Loot is made to be fair and it pushes you to explore the map.
You can bring a partner or get paired up in the lobby. Expect open dunes for long range fights and tight ruins for close up battles. The event is on Java 1.20.1 and it is whitelisted so you have to join first and get your IGN added then show up early for the briefing and kit selection.
