I used 3ds Max and Unreal Engine 4 to make 3D models of buildings and props for World at War: Operation Somalia
Something I did on a team making a FPS very early on in my career but it was fun to work in this team and I learned a lot about working in a team. A Small map made for a game called "World at War: Operation Somalia" where I did the Main menu and basic top down map graphic, along with the level map for the multiplayer in unreal engine.
