This is our first flash game release. We are currently working on adding more information to the game, because its a little vague right now. Click on the blurred-out bum in the beginning to begin gameplay. Place bum mercenaries down to have them throw objects at passing motorists. Click on the bum once it has been placed to see its next upgrade. To use the towers, just place it down, then click on it to select it. Once it is highlighted, click on the bum you wish to place into the tower. Good luck, and please leave comments. Please feel free to visit our site at www.bumdefense.com.
