Good afternoon Aken,
Yes, IF did purchase The Repopulation, however that is being developed by a separate team from the HeroEngine engineers.
The Repopulation remains to be a stand alone game and is not part of HeroEngine or its assets. I am sorry. We do have and include some placeholder assets both in engine and as separate downloads in your dashboard under "Additional Downloads". This includes a couple characters and some static art tile sets.
Regards,
Sarrene'
