Gamble PvP

Turns the co-op survival run into a 3-day free-for-all. Take loans, wager head-to-head, hire goons, snitch on rivals, haunt the living after you die. The mob still wants their cut.

What it does

Multi-day match. Host adjusts day count (1–10, default 3) before play. Hard stop at the final day, then a podium screen with payouts.
Per-player ledger. Every bet's win or loss attributed via MoneyManager. Your wealth = starting stake + cumulative gambling delta − active loan payback owed.
Daily bankroll boost. Day 2 adds 2× starting cash, day 3 adds 4×. Comebacks stay possible.
House clawback ending. End-of-final-day: outstanding debt comes off the top, survivor with the most cash wins. 50/30/20 weighted payout for top 3.
Death cutscene routing. When the game ends, host transitions everyone to LoseStateScene so the mob-death sequence plays under the standings overlay.

The booths

A cluster of three glowing kiosks spawns near the nearest casino game when you enter the casino floor:

Loan Shark (gold)

Day-scaling principal cap ($500 day 1, $1000 day 2, $2000 day 3)
Stacking loans, escalating interest: 1st = 1.5× → 2nd = 2.5× → 3rd = 5× → 4th attempt = instant death
Good-customer discount: pay back a loan and your next same-day loan is 1.25×
Default at day-end = wounded (red vignette + half bankroll the next day, then clears). Default on final day = death.

Wager Booth (blue)

Head-to-head coin flip vs. another living player
$50 / $100 / $250 / $500 stakes
60s cooldown per challenger, 50/50 RNG

Mob Favors (red/black)

Snitch (free): 50/50 RNG. Win → target loses 25% wealth, you get 10% finder's fee. Lose → you pay a 10% false-accusation fine. 30s cooldown.
Hire Goons ($500): Pay $500, target loses $750. 90s cooldown.

During play

Happy Hour: Random 30s windows every 60–120s where all casino payouts are +50%.
Right-side player widget (base game native): Repurposed to show live PvP wealth (net of loans owed), sorted descending, green-up / red-down. The same nameplate art the base game uses.
Profit line graph (base game native): Repurposed to track cumulative PvP wealth across the day.
Tab stats panel: Per-day per-player ledger snapshots with delta-coloring (green/red), gold/silver/bronze ranks, auto-sized for any day count.
Local HUD (top-left): Current day, wealth, active loan + payback owed, wounded/dead status.
Lobby UI (top-right): Host adjusts days per game from any pre-casino scene. Press F2 to toggle the picker anywhere. Use + / - / 0 keys to bump the day count (mouse can't reach IMGUI buttons during gameplay due to camera lock).

Round-end summary

The base game's "STATS FOR DAY N" screen gets fully repurposed:

Title becomes "PvP Standings · End of Day N"
Top stat bar shows your Loans taken, Sabotages used, Wagers Won (replacing the legacy QUOTA/BALANCE/PROFIT)
Profit graph shows your cumulative PvP wealth
Right box shows ranked player standings with $wealth, plus PvP ticket awards:
- +2 🎟 per surviving player
- +3 🎟 to top earner
The shared ticket pool credits the base game's UPGRADES screen — earn PvP, spend on upgrades

Ghost Mode

When you die, a panel appears bottom-right with a target cycler and a HAUNT button. Once per minute you can curse a living player for 30 seconds — their casino payouts are halved while haunted. Losing isn't the end of the game.

Installation

Install via the Thunderstore mod manager — click Install. All friends must install the same version for multiplayer to work properly. Manual install: drop GambleWithYourFriendsPvP.dll into BepInEx/plugins/.

Config

BepInEx/config/com.chals.gamblepvp.cfg exposes:

InterestMultiplier — first-loan interest (default 1.5)
InterestMultiplierAfterPayback — good-customer discount (default 1.25)
StartingMoneyPerPlayer — day 1 starting cash (default 1000)
DaysPerGame — match length (default 3)
StripQuotaCheck — disable mob-kills-you-on-miss-quota (default true)

Known limitations

No sound effects yet. Unity 6's runtime audio API is broken for procedural clips; will revisit when the engine cooperates.
Booth visuals are primitive geometry. Functional, not pretty.
Mixed-version multiplayer is unsupported. Update everyone at the same time.
