Works great as is, however when using ranged it doesnt stop when you run out of ammo (very botlike). Get a bunch of ammo beforehand and your golden. A cool thing to add would be support for telegrabbing valuable drops from the zoo cages.
It does what it says on the tin. used this to 90 ranged flawlessly. I seriously can't fault this in any way other than that it doesn't stop when you're out of ammo. Go with plenty of ammo and you're guaranteed a great experience.... even after 17 months without an update. I also heard the author left around a year ago. Clearly quality.
