50 rounds of .45ACP flying about would be OP'd dude.
Not if you can barely damage the enemy you're shooting at due to a high damage threshold.
he said there are no Thompsons or Brownings.
To be fair if it WAS in in the game, it would probably be given a stupid generic name istead of its actual name anyway...
Though it does strike me as odd that they didn't add it, considering how many people clearly wanted it and that it would fit pretty well with the game. And they've added other real guns to it, or at least, guns that LOOK exactly like real guns but for some mysterious reason are referred to by generic names like "assault rifle", so I do wonder why they didn't add a Tommy Gun. I do hope that they're not going to just add it in a DLC, though, if they're going to put such a demanded weapon in the game, it should be in it from the start, not added later as a DLC, oh well, I'm quite certain that someone will make a mod that adds it eventually. The only problem with that is that the quality of mods can very a lot, and the end result could be anything from a lot better looking than anything Obsidian would have made to something that would have looked more at home in the original Half-Life than any modern game, whereas with things designed by the developers, we can usually expect a consistent standard in quality.
