Can you tower over your opponents? In this game, you enter the battlefield against three other opponents. Each player owns a tower with the most number of soldier units. Your goal is to attack neutral towers and then take over your opponents' towers. You win when you overthrow all your opponents!! There's many ways to go at this:
Accumulate skill points and coins to upgrade attack, defense, speed, and more. The choice is yours!

Left mouse click to select towers to send your units to raid. Click & hold to select and release. That's it, if you have a mouse, you're ready for the battlefield.

So-----Do you have what it takes to dominate the battlefield and be the last player remaining?!
