KFRPG Server Fundamentals: XP, Perks, Pets and Turrets

KFRPG is a heavily modded Killing Floor 2 server that adds levels, prestige, a custom perk tree, pets, player-built turrets and extra weapons. This guide collects the basics a newcomer needs before joining. At the time of writing (2017) the server was reached with the console command OPEN 70.42.74.127:7777, and news was posted in the KF-RPG Steam group; the address may have changed since.

XP: how to get it and spend it

XP comes from tagging ZEDs. One point of damage is enough to count as a tag, killing is not required, and every player who tagged a ZED gets the same amount.

Press Esc in-game on the KFRPG server and open the modded Perks menu, then the "Perk" tab.

The Perk tab of the KFRPG menu.

Every level gives perk points that you spend on class perks and traits. Choosing a different class on the left lets you view and edit that class's points, and this is also how you switch class in-game.

Perk points are shown per class.

Prestige

At level 200 you reach your first Prestige. The Prestige button resets the character so you can level from the start again, but each level on the next run grants one extra perk point, so your total pool grows. Prestige appears as a prefix to your level, for example "4-125" is Prestige 4, level 125. The current maximum Prestige is listed in the news section of the game menu.

Prestige resets your level and adds a perk point per level.

• Unload Perk refunds all spent perk points while keeping level and Prestige. It costs some XP, but is worth it after a mistake.
• Reset Level is drastic: it sends you back to level 0 and Prestige 0.

Use Unload Perk to re-allocate points, not Reset Level.

Waves and the endless wave

Each map has 7 standard waves balanced to the number of players, then one Boss wave (also balanced), then a final Endless wave. The Endless wave keeps spawning ZEDs until all players are dead or a map vote passes (type !mapvote in chat).

• No new player can join once the Endless wave starts.
• Players can respawn for $10,000.
• Money can still be gained while dead if one of your turrets is alive and loaded.
• Kills keep counting up and the spawn limit is infinite.

The Endless wave counts kills without a spawn limit.

Regen perks

There are three: Ammo, Health and Armor Regeneration. Before Prestige 1 you can have only one. At Prestige 1 a second regen unlocks, but only after level 100. At Prestige 5 and above a third unlocks at level 150.

Regen perks and their unlock rules.

Ammo Regeneration refills ammo of all weapons up to their caps (not hand grenades). Health and Armor Regeneration restore a portion of health or armor up to the cap.

Pets

At level 50 you can buy the Monster Tongue perk (it also needs 30 points in Perk Damage), which gives you an auto-respawning pet. Pets do not spawn in Endless waves, can be healed, absorb Medic darts (which can get in the way of healing players), tag ZEDs for you, and their kills count as yours.

Monster Tongue level	Pet
1	Crawler King / Clot AlphaKing
2	Gorefast DualBlade
3	Husk
4	Scrake
5	Fleshpound
6 (Prestige 25)	Tyrant

Modded weapons

M79 Medic Launcher, M79 Frost Launcher, Horzine AK12, Tigris, Galantine, Flaming Katana and Horzine Grenade Pistol. Primed weapons are the strongest version of a weapon and can never be dropped.

Turrets

Buy the Sentry Turret hammer (it looks like the Pulverizer), equip it and read the on-screen help. Hold alternate fire to preview the turret, release it to place. Watch the bottom of the screen for messages: too close to another turret, or the 12-turret map limit.

• Primary fire with the hammer heals any turret; alternate fire on a turret destroys (sells) it, so be careful.
• Stand on a turret and press E ("Accept Objective") to open its menu with Levels, Upgrades and Ammunition.
• Anyone can upgrade, resupply and repair anyone's turret.
• Turrets generate XP tags and dosh. They count as off-perk for all classes, so Off-Perk Damage improves them.
• If you place a turret where you can no longer reach it, you must disconnect and reconnect to remove it.

ZED announcements

• "By fire be purged" - Husk
• "Meeeat" - Meatgrinder
• "I am power incarnate" - Tyrant
• "Now you feel pain" - Puke Pus
• "You are not prepared" - King Tyrant
• Foghorn sound - Golden Clot spawn
• "It's me!" - Gilded Clot spawn

Events and event maps

An event is the spawn of Golden Clots, announced by a loud horn. An event map has an unusually high number of events each wave. Golden Clots are worth the most XP in the game, so tag one fast; if nobody kills it quickly it despawns and nobody gets XP.

Tag Golden Clots as soon as they spawn.
