01 / MULTIPLAYER
Online co-op
Shared contracts, synchronized combat and persistent characters for 1–4 players. Multiplayer logic is integrated with the same progression systems used in solo play.
Cyberpunk Action RPG
PROTOCOL: VOID
A fast-paced pixel-art action RPG built around deep character customization, randomized loot, contracts and online co-op.
StatusIn development
Players1–4 online
EngineGameMaker
PlatformSteam
Project overview
Built at
4Tins Studios.
Build a character around weapons, skills, implants and gear, then push through contracts, crafting and increasingly demanding endgame content.
SYSTEMS CASE STUDY
How PROTOCOL: VOID is built.
Five systems that show the technical scope of the project. Visual examples will be added directly to these sections.
02 / LOOT
Item & build system
Randomized equipment, affixes, Relics, Prime items, upgrades and skill-modifying effects designed to create many viable character builds.
03 / ENDGAME
Contracts & mapping
Repeatable contracts and Data Disk systems combine procedural content, difficulty scaling, targeted rewards and endgame progression.
04 / ECONOMY
Crafting & player market
Crafting, vendors, recycling and an online market connect item progression with a player-driven economy and persistent ownership.
05 / BACKEND
Persistence & backend
Supabase-backed character and item persistence, Steam-linked authentication and server-side ownership data for online systems.
