I developped a small online 2 player head-soccer like game with a rollback engine

Overview

Head-Shot is an online multiplayer game inspired by Head Soccer, developed in C++ with a custom rollback netcode engine. The project was a deep dive into real-time networking, latency compensation, and deterministic game logic.

The primary challenge was implementing a rollback engine to ensure smooth online gameplay, even under high latency conditions. This involved synchronizing game states, predicting player inputs, and efficiently handling network corrections to maintain a good gamefeel.

Beyond networking, the game features physics-driven character movement, responsive controls, and competitive gameplay designed for fast-paced matches. Developing Head-Shot provided valuable experience in networking architecture, low-level optimization, and multiplayer game design.

Head-Shot uses “Bark” my own physics engine.
