Complete HL2:DM server.cfg reference — hostname, GSLT, gravity gun settings, and physics tuning.

HL2:DM uses server.cfg in hl2mp/cfg/.

Key Settings

hostname "My HL2:DM Server"
sv_password ""

sv_lan 0

Create at Steam Game Server Management with App ID 320. Add +sv_setsteamaccount TOKEN to startup.

HL2:DM's gameplay centers on physics objects and the gravity gun:

Setting	Default	Description
`sv_gravity`	`600`	World gravity (lower = floatier)
`phys_pushscale`	`1`	Force multiplier for physics objects
`physcannon_maxforce`	varies	Gravity gun pull force
`physcannon_maxmass`	varies	Max mass the gravity gun can lift
`physcannon_tracelength`	varies	Gravity gun grab range
`physcannon_mega_enabled`	`0`	1 = Super gravity gun (blue, like end of HL2)

Set mp_teamplay 1 in server.cfg for team-based play instead of free-for-all.
