Wiinick The code for tribu's zombies is complex for what he needs them to do. He creates an entire new Zombie class and piggy-backs minecraft existing zombie code. It's bit much for what his zombies do. The zombie AI I use doesn't require a special Zombie class and thus less code and higher performance rates. Although maybe not noticeable at first, over time Tribu's zombies begin to get strange as the count get's higher (but this is likely because they're a lot of entities anyways, and we all know if you have a lot of entities things start to happen regardless of the type of entity) On the other hand, you can setup signs to buy items with this plugin. Maybe not kits, but whatever, use an economy plugin for kits. You can also setup signs for live stats (player count, wave, zombies in map) There's also Mystery-boxes which can be purchased. Also if you want to see more features just ask for them. I'm always up for adding features. On a side note, Tribu has over a year heads start on me. This plugin is just 1 month old and I will boast a small bit and say for being just 1 month old compared to Tribu, I'd like to say I've done a lot better job on adding features, and updating.
