It's really cool overall and I bought this game primarily for mods like this, but:

1. Killing George in solo should get you the Wunderwaffe, yet it doesn't and gives you the Death Machine. Idk how no one seems to remember this about the original.

2. Moving in the water is painful. Jumping should be able to move you through it faster, but if anything it slows you down and having the Death Machine is a literal death sentence in the water since you basically are completely still if you even try jumping with it.

3. Zombies melt you way too quickly. I'm not sure if it's a Black Ops 3 thing, but getting quadruple tapped when near a zombie for half a second should just not be a thing. Being in the water is then so much scarier because of this, coupled with the awful movement in the water.

4. Pretty sure you could get Quick Revive 3 times, meaning 4 total lives, but you can only get it twice here. Also, the jingle keeps playing despite the perk machine disappearing.

5. George, like zombies mentioned in point #3, melts you way too quickly as well if you don't have jug. I should be able to run past George, piss him off, and NOT die, yet that doesn't seem to be the case in tight hallways like the one-way coming back to spawn or the top of the lighthouse.
