Underground Invasion

Free Action Defense Games
Developer: DMT (Developer Machine Team)

You must defend the sewers from a various onslaught of creatures in this pretty visually striking take on the classic 'tower defense' genre. The game provides a decent amount of weapons and upgrades, most important being the turrets, which can be placed around the sewer to help defend against the seemingly unending flood of swamp creatures.

You are the defender of Warcoder City, and the object of the game is to keep the sewer bars from being penetrated by the enemy. There are Five sectors, with five levels in each. The difficulty increases steadily so it is a good idea to be very strategic about what weapons and upgrades you choose. You also must manage to protect the walls of the sewer as well as the bars below.

The artwork is quite impressive with a good amount of gnarly-lookin mutant enemies. The pretty extensive amount of upgrades and enemies makes the game more engaging than your usual run-of-the-mill tower shooter. The ambient soundtrack and sound effects are perfect.

Controls / How To Play:
Use your mouse to aim, left mouse button to fire. Number Keys 1-5 select your weapon. "R" key reloads, "A" key enters edit mode where yo can place your turrets, use various items, and repair damage.
