Hurtgen Forest is more a representative level, but was based on a geographical real world area. I was tasked with remaking the original Hurtgen Forest level for Hell Let Loose, which suffered from performance issues, technical issues, and a lack of cover for players. I think I ended up adding too much concealment, but it did end up performing better thanks to the expertise of Danny Ivan Flu! I would love to see an entire game like Hell Let Loose dedicated to the Hurtgenwald campaign.
Thanks to all the hard work from those who worked on Hell Let Loose. Special thanks to Danny Ivan Flu, Grytzen Jetze Veenstra, and Max Rea.
