My WIP project

GDT Survivor

An isometric spaceship shooter. The goal: maneuver through asteroid fields, shoot down enemy fighters, mine resources and upgrade your ship. Solo or in online multiplayer.

GDT Survivor dogfight: enemy fighters closing in on the player ship between asteroids and nebulae

Built by the RheinMain GameDev Team at Hochschule RheinMain. Three of us, with Martin Weier and Lam Trinh. Started with Unreal Engine 5.4, in active development since 2024 (with breaks here and there ;)). A first pre-alpha is out now on itch.io.

Everyone on the team picks their own focus. I built the controller-driven UI with CommonUI and the homing-missile target acquisition. Each of us implemented our own gameplay mechanics. Save logic, multiplayer, weapon logic and enemy behaviour. Right now I'm working on the enemy-wave mechanics.

Engine: Unreal Engine 5.8
Languages: C++, Blueprints
Role: Gameplay & systems programmer
Team: 3-person team, since 2024
Status: Pre-alpha on itch.io

Dev notes

I jot down what I learn along the way. Engine architecture, C++ basics, and whatever else comes to mind. On LinkedIn.

Who owns the data in an Unreal game? GameInstance, GameMode, GameState and the HUD. A way to remember which class is responsible for what, and how they talk to each other in GDTSurvivor.
