What Is the Peacock Project?
The Peacock Project is an open-source replacement for Hitman’s official online servers. It runs entirely on your local machine, eliminating the need for an internet connection while restoring full online-like features: leaderboards, progression, elusive targets, escalations, and more.
Key benefits include:
- Preservation of the trilogy (Hitman 2016, Hitman 2, and Hitman 3).
- Immediate access to all unlocks and items.
- Support for server-side plugins and custom content.
- Regular community updates and exclusive escalations.
Without Peacock, most advanced mods like HiMark’s Mission Pack simply won’t function, as they rely on server-side logic for contracts and progression.
HiMark’s Mission Pack: Features and Content
HiMark’s Mission Pack transforms the standard Hitman experience by injecting new narrative-driven contracts and challenges. Creator OhHiMark focuses on quality over quantity, delivering missions that feel official.
Core Features:
- Custom Missions & Contracts — Unique stories, “Kill All” variants, and creative uses of existing locations.
- Elusive Targets & Special Assignments — New ETs (some fully custom) plus reused assets in fresh contexts.
- Outfits & Items — Custom suits, a new weapon, and reused gear integrated seamlessly.
- Localization — Support for English, French, Russian, and six other languages, thanks to community contributors like MLuka47 and SinfulMoonson.
- SMF Options — In-game toggles to customize difficulty, enable/disable specific content, or adjust loadouts.
- Challenge Integration — New opportunities and mastery paths that tie into the base game.
The mod includes detailed spreadsheets for mission lists and challenges, making it easy to track progress.

Why Players Love the Peacock Project Himark Mod
The official servers have limitations — discontinued support for older titles, restricted modding, and occasional downtime. Peacock + HiMark’s pack removes these barriers. Players gain:
- Endless replayability through custom content.
- Creative freedom (e.g., “Kill Everyone” campaigns with complications).
- A thriving community that releases new plugins monthly.
HiMark’s pack shines because it respects the source material while adding fresh twists. Missions blend stealth, action, and humor in ways that feel like lost IO Interactive DLC.
Risks and Best Practices
Stick to official sources: Peacock GitHub, Nexus Mods, and the Peacock Discord. Avoid shady third-party sites claiming “enhanced” versions. Always scan downloads. Back up your game files before installing large packs.
Use SMF’s built-in options to disable content if performance dips on lower-end PCs.
