Since atlantica online has 0 detections its easy to make bots or hacks for the game. A great one to use would have to be cheatengine. Keep in mind they do store most of their things server side so you cant manipulate your health or anything. But you can more than likely create a speed hack and teleportation hack with this. Enjoy.

If you use cheat engine, you just need to search for the current speed In the game till you get the right adress.
120 = Very fast
80 = Very slow
You can change it to what ever, but to have it 100% Stable the highest value is around 240. I use personally 360, but sometimes it stuck at some skills or at fast mobs.
