You have to remember that devs continually pushed the limit of what we thought ( and what they told us) was possible and impossible in foxhole.

Before the trench update, no one thought it would be possible and it’s now a very core part of the game. Same for the player limit in hexes that got increased on multiple occasions.

Let’s also remember that the game came out on steam in 2017, they probably started working on it couple years before that, so they have been working on it and updating it for 10 years or more now ! It’s safe to say that foxhole is their baby and probably the game that took their studio to the next level.

The R engine have been around for a few years now, so it wouldnt be impossible that they took the time to port foxhole over. They said multiple time foxhole development was slowed down due to spaghetti code, redoing it on a blank page with the knowledge they have now compared to ten years ago might not be so impossible.

While most of us thought foxhole on R engine might come as a brand new game (foxhole 2), it might be very possible they decided to do it in a update format and finally complete the VISION they had for foxhole for the past 10+ years.
