As a personal project I maked a Multiplayer FPS in C++ and Blueprint with 5 different weapons and two game modes: Free for all and Team Deathmatch.
In this game I have studied and designed network components such as Lag Compensation, Server Side Rewind and Client Prediction using STEAM network as infrastructure.
I am currently modifying it by making it from a third-person game to an FPS by going to create the various blend spaces of the animations.
