Screen shots from the UE4 demo of World War II online which I half lead development of. I was responsible for all terrain, lighting, roads, general engine work and fixes. None of the models here were made from scratch, they are either from the asset store or converted from the original game by other team members since we did not have the time to create new assets. This is more a proof of concept of what the game could look like inside UE4 instead of a new playable demo. To my surprise, I experienced no performance issues when actually 'playing' the demo, so I imagine that this is perfectly playable.

Note: I did not take these screenshots, they were uploaded here with permission and can be found in the original post: https://www.wwiionline.com/company-news/the-future-of-wwii-online
