The combat in this mod is frickin amazing!!! I've got it on hard and I'm getting my ♥♥♥ kicked thanks to currently having to use 1 Index controller and 1 Vive wand controller (other Index is in RMA state). Wow!

I hope there's a mod for the actual HLA campaign that adds a ton more enemies and a lot more ammo, and actually makes the campaign a tough challenge. Finishing the HLA campaign needs to feel like an achievement that was hard fought and didn't come easy.
