Zvampext RPG is a Killing Floor 2 ServerExt revamp focused on RPG perk progression, custom trader support, and stable Endless server play.
The mod keeps the original package names, ServerExt and ServerExtMut, for
compatibility with existing ServerExt servers and clients.
The Steam Workshop page is the release hub for players and server hosts:
When reporting bugs, include the map, game mode, difficulty, wave or trader state, active perk, loadout, active mods, crash text, and any useful screenshots or logs. Detailed reports are much easier to reproduce and fix.
ServerExtMut.Zvampext_Endless.ServerExtTraitIcons.upk.KFZvampCustomItems.ini.Use Zvampext’s owned Endless game class:
?Game=ServerExtMut.Zvampext_Endless
Recommended first mutator stack:
?Mutator=ServerExtMut.ServerExtMut,TraderGuard.TraderGuardMut,ZedSpawner.Mut,ZedCosmetic.ZedCosmeticMut,TF2SentryMod.SentryTurret
Recommended first launch shape:
KF-MegaBiotics_v2?Difficulty=3?Game=ServerExtMut.Zvampext_Endless?AllowSeasonalSkins=0?MaxPlayers=64?Mutator=ServerExtMut.ServerExtMut,TraderGuard.TraderGuardMut,ZedSpawner.Mut,ZedCosmetic.ZedCosmeticMut,TF2SentryMod.SentryTurret
Do not add TIM.TIMut, external Controlled Difficulty game classes, or trader
replacement mutators to the first setup pass.
For Linux dedicated servers, add the Workshop item to
LinuxServer-KFEngine.ini:
[OnlineSubsystemSteamworks.KFWorkshopSteamworks]
ServerSubscribedWorkshopItems=3726663955
Make sure Workshop download is enabled:
[IpDrv.TcpNetDriver]
DownloadManagers=OnlineSubsystemSteamworks.SteamWorkshopDownload
DownloadManagers=IpDrv.HTTPDownload
DownloadManagers=Engine.ChannelDownload
Recommended first KFServerExtMut.ini Endless section:
[serverextmut.Zvampext_Endless]
ZvampextMaxMonsters=0
ZvampextWaveSizeFakes=0
bZvampextCompatVerboseLog=False
bZvampextEnableMaxMonsters=False
bZvampextAutoPauseTrader=False
ZvampextWaveTotalZed=0
bZvampextEnableWaveTotalZed=False
bZvampextStopOnCrashRestart=True
bZvampextCrashRestartArmed=False
For V2.0, avoid using URL MaxMonsters as the main spawn control. Use
ZedSpawner for custom spawn behavior.
Old KFZedSpawner.ini configs can usually be reused. If a zed package is not
installed, comment out that spawn row and keep the rest of the config.
Safe first-test pattern:
Spawn=(Wave=2,ZedClass="ZedCustom.BlueHusk",Probability=5,SpawnCountBase=1,SingleSpawnLimit=1)
Spawn=(Wave=3,ZedClass="ZedCustom.RedScrake",Probability=5,SpawnCountBase=1,SingleSpawnLimit=1)
Spawn=(Wave=4,ZedClass="ZedCustom.BaronHell",Probability=3,SpawnCountBase=1,SingleSpawnLimit=1)
Start conservative:
Probability=3-5
SpawnCountBase=1
SingleSpawnLimit=1
Raise counts only after several waves survive cleanly.
Custom trader items belong in KFZvampCustomItems.ini.
Example:
[ServerExtMut.Zvamp_CustomItems]
bAddNewWeaponsToConfig=False
Item=TF2SentryMod.SentryWeapon
StorePrice=TF2SentryMod.SentryWeapon=5000
Use one Item= row per weapon. The value can be either a weapon class or a
weapon definition class.
Use StorePrice= to override trader price:
StorePrice=TF2SentryMod.SentryWeapon=5000
After editing item rows while the server is running:
admin ZRefreshnewitems
or:
admin refreshitems
Restart the server after adding new package files.
TraderGuard is used as a conservative trader helper. It is useful for sell aliases, public trader controls, and custom trader safety. It is not intended to replace the Zvampext trader or rebuild owned items automatically.
Recommended safe settings:
bUseExperimentalAllItemsSellLookup=False
bFastPurchaseHelperRefresh=False
bUseStateCheckpoints=False
bAutoRebuildOwnedItemsOnTraderOpen=False
bAutoRebuildOwnedItemsOnTraderMenuOpen=False
Use SellableWeaponAliases= only when an owned weapon does not get a proper
sell button or sell value.

TIM and CTI are respected parts of the ServerExt ecosystem, but they are not recommended as runtime mutators for the V2.0 baseline.
Use this safer approach instead:
KFZvampCustomItems.ini.ServerExtMut.Zvampext_Endless.| Mod | Status | Notes |
|---|---|---|
| ZedSpawner | Recommended | Best path for custom zeds. Old configs can usually be reused. |
| TraderGuard | Recommended | Keep conservative settings. Use for sell aliases and trader controls. |
| ZedCosmetic | Tested | Works in the current compatibility stack. |
| TF2 Sentry | Tested | Add the Sentry Hammer through KFZvampCustomItems.ini. |
| Loot Beams | Likely safe | Watch dropped weapon, pickup, and sell-list edge cases. |
| FriendlyHUD | Likely safe | Test after perk/trader UI is stable. |
| Auto Healing | Conditional | May overlap RPG perk balance. |
| Bonus Zeds | Conditional | Prefer porting desired spawns into KFZedSpawner.ini. |
| Zed Varients | Conditional | Use pawn classes through ZedSpawner, not the mutator. |
| Zedternal Zeds | Conditional | Use as a class library through ZedSpawner. |
| TIM runtime mutator | Hold off | Import item rows instead of running TIM. |
| TraderDash | Hold off | Overlaps trader skip and trader state behavior. |
| Unofficial Patch | Hold off | High overlap with UI, trader, inventory, and HUD changes. |
| External Controlled Difficulty game classes | Hold off | Zvampext should own the game class for V2.0. |

Zvampext builds on years of ServerExt community work.
