Suggestion

1. Sounds like a good thing to have.
2. Crossbow is already good, it has no recoil and good dmg overall.
3. More grenade upgrades would be great.
4. No reason to buff the dmg, Glock can kill zombies pretty easily and if u get to level 7 u get mac 10 which is a pretty good weapon even for higher levels. It does around 350 dmg for a headshot if I remember correctly.
Also, the tank is supposed to be hard so no reason to complain about it, if u you play smart u can solo even with a lower level.

You can't solo tank with lower level, because tank is 2x faster than new player and tank with good aim can simply 1 shot human. Mac 10 is not that good for ne player, they don't have damage upgraded as u do, they do about 100-200 headshot and about 50 body shot
