I would usually be sad to see another original RPG go 5e compatible but Neuroshima was infamously poorly designed ruleset, possibly worse than Shadowrun. I probably won’t be running it, but may steal statblocks for my 5e game if I need weird stuff again.
And the book is horrible. Want to throw a grenade? Let me check under grenades… No, not there. Let’s check under the throwing skills. Nope, no throwing rules for weapons. Well, maybe under attacks? No, that doesn’t have grenade throwing rules either.
Oh look, here in a completely seperate section, contained in an unlisted sidebar, are the rules on grenade throwing.
Wait I found a reference to the page…and it’s not actually the right one.
Or in some editions:
Want to build an explosive? Here’s an equation you haven’t seen since 9th grade that determines how big an explosive you can build.
