It looks like the author of the Running with Bolters mod found here: viewtopic.php?f=7&t=496
fell off the face of the earth, and the mod is not compatible with the current version of the game.
Are there any plans to add compatibility or allow us to revert the game to an earlier version?

Once I start getting the hang of modding this game I am most definitely going to try and convert this mod.

Now I'm officially working on updating the mod to the best of my ability!

If you'd like to help out feel free to PM me!
