It had an alright playability. It wasnt boring even if the balance and map design weren't good. It was fun and I could probably play it a second time. Some of the triggerwork was faulty or not entirely done. But on a whole the triggerwork was good!
To be honest, It wasn't very balanced, most of the time your team is too overpowered, but at the end with the giant zombie army, it is nearly impossible. The Zombie slayer with a degree was overpowered, as was the super zombie slayer. But it wasn't too bad for a first try.
It was Creative enough, although you could have put in more of a story, like the super guy could have had a background, and given more of an explanation as to what is going on. It was a good Idea, (even though it has been done before) and deserves a 3.
Map Design: 2
Not much eyecandy, most of the terrain was grass A. All of your players were generic names (player 1, player 2, player 3) you could have done better for this. With a bit of eyecandy, terrain mixing, and little sub-quests, this would be better.
There was no instructions besides look around, I mean you couldve had objectives and more guidance. Also, when you get the automatons, it says a swear word. I dont mind, but there are alot of people on AoMH that would ban this.
Sorry for the harsh-ish review, I know it is your first uploaded map, and it is pretty good. Although with a bit more work it could be really fun, If youre going to update it I would look forward to it!. :)
