Tower Defense is begining to get back on its feet.
I'm planning on one update a week from here on out until I deam it finished. As it stands right now there are 20 waves, 16 towers that will be broken up into different classes and tech levels at a later point.
The waves are split up into groups of 5 called sagas. Sagas usually have a specific trait that pertain to all monsters within the wave. The sagas are currently as follows, the Beginner Saga (i.e. basic enemies with a slightly odd one at the end), the Remembrance Saga (i.e. enemies brought back from the original Tower Defense), the Final Fantasy Saga (i.e. holds most of the playable characters from Final Fantasy VI - X), and the Odd Saga (i.e. strange things like floating pies and loads of rabbits.)
There are 5 difficulties accessible from Very Easy to Very Hard, the harder the difficulty the more points you earn per kill, points are used to determine ranking on the Byond Hub. Also in the harder difficulties it almost becomes necessity to cooperate with others to win.
Once you have finished an entire set of monsters the skill level increases and the queue of monsters begins again but at a much higher difficulty, this can continue to the point where it is literally impossible to kill anything.

There are two gameplay modes to Tower Defense as well as the 5 difficulties. You can opt to play versus mode which consists of two teams, The North and The South, duking it out by hiring monsters to run thier opponents defenses and try to make it safely to town with out being killed.
This game mode is best played with 4 to 8 players, although it can be played with 2.

In the very near future I will be open to suggestions for sagas to add to the game.
Also in the future depending on the request for it will add some midis from a friend and a few various websites into the game. These midis will be chosen from a menu and played throughout the world. Here is a compilation of some of the midis chosen, Midis.zip. Feel free to use these as you wish.
