Needs more tower types or a sequel

This was my favorite tower defense game, needs more tower options: a tower that creates exploding balls of matter; the upgrade path uses red balls of matter that explodes ending with the nuke upgrade while the second upgrade path creates black balls of matter that creates blackholes damaging enemies that touches it, a laser tower that at enemies nonstop with a second upgrade path that converts to a laser fence that creates a laser barrier with upgrades that extends the length and damage and a flame tower that shoots fireballs that damages enemies in a small area and over time with the second upgrade path that converts it to a flamethrower shooting cones of fire with area effect damage. try adding these or make TriDefense 2 and put these features in the game.

Can easily become an obsession

I find myself returning to this game fairly often. It is fun to set up battlefield strategy and watch it play out. The cool part is the enemy is always adapting to your moves and always increasing the intensity of the attacks, so the game keeps you hopping around trying to stay ahead of the action. Your weapon funding source is tied to your successful kills, so you must deploy your weaponry in a manner that keeps your purchasing power replenished quickly. If you like battlefield strategy games, give this a try.

Great Game

I was looking around for a decent tower defense game that wasn't too outlandish and required some thought and attension. I didn't think that would be hard, but it was. Fortunately, I found this game and enjoy it entirely. If you're anything like me, and you're looking for a challenging, semi-realistic TD game, this will likely be your new favorite.
