I can confirm that i am working on a map, but i haven’t used E1M4 as a guide at all. I was actually hoping we’d make a Doom 2 map pack, but it looks like that idea now has been rejected 🙁
I couldn’t even remember what E1M4 was, tbh, But i have played through it, and I will endevour to produce something similar in size, content, and hopefully quality.
I aim to have it done by the weekend. 🙂
