1 / 9
The multiplayer add-on for Gatling on FishNet.
Each shot crosses the network once as a small fire order every peer replays, so bandwidth follows shots fired rather than bullets in flight, with lag compensation and per-shooter hit authority. Gatling is required and sold separately.
Your Gatling weapons, rounds and impact rules run on FishNet, host and clients, without being rewritten. There is no NetworkObject per projectile, so a shotgun blast costs the same as a pistol round, and spread and wind match on every screen.
The server judges a shot against what the shooter actually saw. The shooter sees the shot at once, corrected by the server, and mismatched builds are refused at connection so two players never fight with different guns.
One menu entry turns an empty scene into a networked session that fires: press Play, then Start Host.
What you get
One fire order per shot
25 to 37 bytes for a typical order, 9 bytes to end a burst.
Lag compensation
Server-side rewind with server-measured latency, capped by Max Rewind Ticks.
Hit authority per shooter
ServerOnly by default, Shooter, or Shooter With Server Validation.
Late joiners
Players who join mid-match see the shots already in the air.
Relevance filtering
Opt-in, by region.
Diagnostics and docs
Live network diagnostics in the Gatling window and more than 40 searchable documentation pages.
7 networked samples
Showcase arena, PvP range, 2D bullet hell, thrown objects, traps and turrets, wind range and stress bench.
