RTF is a global modification that replaces all towns in the game.

Of course! I used to do that myself, and even posted it on the forum. I'm a bit embarrassed now because I didn't even ask for permission, but you can post it too if you want.

Thank you!
I've reworked your mod, now the Rotting Guard replaces the Zombies.
I've added a description and tweaked the text for the buildings, Orson's specialization, and the weeks.
I've adjusted the balance; now they're somewhere in between tier 2 and tier 3.
I removed the Double Strike and Assault abilities from the alternate upgrade because three strikes are too much, in my opinion.
