Keep in mind, FOnline is not Fallout 2. We use a completely different engine that just looks and feels like Fallout 1 / 2.
Like written in the newspost, the first wave of 3d models will be some animals, which come with the next wipe. With them, we will test how it runs for everybody and fix bugs, etc. After this and when human characters are ready (more weapon models and armors, etc.), they will be introduced. This is depending on how fast we can recreate the missing content.
