Thing is really good, even at Round 27, which is the highest I've gotten.
Only thing is that it takes butt time to reload when you're in a sticky situation. This thing kicks butt when normal, kicks even more butt when Pack-a-Punched.
This gun has like no kick at all, and is better than the ray gun because it has no splash damage! It's like a ray gun but in bullet form. Have you seen the headshot multipliers? This thing is almost overpowered when everyone gets it, while the ray gun struggles on low rounds,20s-30s, the mark 2 still puts in work.
The ray gun mark two is beast and actually is better when packed unlike the ray gun and it can take out brutus, panzer soldat, and hoards of zombies pretty easily.
When my friends and I are playing and one of us gets it, the rest of us really jealous, and literally just hate him for the rest of the round. Otherwise, this thing is literally THE BOSS. The only thing is that when you are using it when there's only one zombie, and you shoot it, the 3-round burst kinda wastes ammo.
