Berserk

A BepInEx mod for R.E.P.O. that adds a toggleable berserk state: bleed health every second in exchange for a big Strength and Tumble Launch boost. Live fast, hit hard.

What This Mod Does

Press B to toggle berserk on or off. While it's on:

• You lose 10 HP every second (configurable — and it can kill you).
• You gain +5 Strength levels — stronger grab/throw force, and everything that reads your Strength level (Armor, the UI overlay, …) sees the boost too.
• You gain +5 Tumble Launch levels — more launch force, and if you run Increase Tumble Damage, your tumble hits land for a lot more.

A pulsing red BERSERK badge appears at the top of the screen so you always know it's active. It turns itself off automatically when you die or leave the level.

It's a glass-cannon trade: enormous burst power for a constant bleed. Pop it for a fight, then turn it off before the drain takes you.

How It Works (and why it plays nice with other mods)

The boost is applied two ways at once, and neither touches the saved upgrade data:

1. Live game effect — exactly mirroring the game's own upgrade-apply helpers, but only on the live components:
   • physGrabber.grabStrength += 0.2 × StrengthBonus
   • tumble.tumbleLaunch += LaunchBonus
2. Stat-level overlay — a temporary additive layer in Character Stats that other mods read, so Armor / Increase Tumble Damage / UI all treat you as +5 while berserk.

Because nothing is written into the game's playerUpgrade* dictionaries, Improve never absorbs the bonus and it's never baked into your .es3 save. The health drain bypasses Armor (it writes health directly instead of going through the damage path), so the bleed is never softened. Everything reverses to the exact applied amount when you toggle off.

Configuration

Settings are in BepInEx/config/headclef.Berserk.cfg or in the in-game mod config menu:

Key	Default	Range	Description
Toggle Key	B	—	Key to toggle the berserk state
Health Drain Per Second	10	0–100	HP drained every second while active
Strength Bonus	5	0–50	Temporary Strength levels added while active
Launch Bonus	5	0–50	Temporary Tumble Launch levels added while active
Can Be Lethal	true	—	If true the drain can take you to 0 HP and kill you; if false it stops at 1 HP
Show Indicator	true	—	Show the on-screen BERSERK badge while active

Berserk itself has no multiplayer setting. If you play as a co-op client, the one switch that matters lives in Relay — see Multiplayer.

Requirements

• BepInEx 5.x installed for R.E.P.O.
• Character Stats — required dependency
• Relay — required as of 1.1.0. Berserk will not load without it. Thunderstore installs it for you; if you install manually, install Relay too.

Installation

1. Install via Thunderstore (recommended) — Character Stats and Relay will be installed automatically.
2. Or manually: place Character Stats.dll, Relay.dll and Berserk.dll into your BepInEx/plugins folder.
3. Launch the game — the config file is generated on first run.
4. Playing as a co-op client? Turn Relay's switch on — see Multiplayer. Without it Berserk will simply refuse to activate, on purpose.

Upgrading from 1.0.x

• 1.1.0 requires Relay. Nothing else changes: every Berserk setting keeps its name, its place and your value.
• 1.0.5 and earlier refused to work as a co-op client (1.0.4 and earlier were worse — see below). With Relay switched on, 1.1.0 works as a client for the first time.
• If you play only single player or only as the host, nothing about your setup changes.

Multiplayer

• Runs per-client — only you go berserk, and only your own stats and health are affected.
• As the host or in single player, both boosts apply in full. Nothing below matters to you.
• Death is fully networked (it uses the game's own death call), so dying while berserk syncs correctly. The drain itself is applied locally, so other players' copy of your health bar may lag slightly until the next sync.

As a co-op client — turn Relay on, or Berserk stays off

Berserk's two effects are Grab Strength and Tumble Launch, and those are precisely the two stats R.E.P.O. computes on the host, from the host's own copy of your character. Your machine is never asked, and every message the game has for changing a stat is host-only by design. So writing them locally does exactly nothing for a client.

The health drain, however, is local and works perfectly. That combination is the trap: all cost, no benefit. Up to 1.0.4 nothing stopped you from activating, so a client burned health for a boost that never existed, while the badge and the stat overlay cheerfully showed a bonus that did nothing.

So Berserk asks Relay one question before it will turn on: can this boost actually be delivered?

Situation	Berserk
Single player, or you are the host	Works — your writes are the simulation
Client, Relay switched off	Refuses, and says why in the log
Client, Relay on but the host does not run it	Refuses — the host never answers, so nothing could land
Client, Relay on for both of you	Works — Relay applies the boost on the host

To use it as a client, you and the host both:

1. Have Relay installed (it comes with Berserk).
2. Set BepInEx/config/headclef.Relay.cfg → [Multiplayer] → Enabled = true, or use the in-game mod config menu.

There is nothing to set in Berserk. If it refuses, the log line tells you which half is missing. Relay ships off by default because an earlier version of that bridge broke multiplayer connect — read Relay's readme before switching it on.

Improve's allocations and Berserk's boost stack rather than fight: both report to Relay, which adds them up and applies the total once. That is the whole reason Relay exists as its own mod.
