A runner in which the player is able to control the force of gravity.

Tower Defense Sudden Attack is a strategy game set in a military base seized by many terrorists and now is under attack.

Now they have not only jeeps and trucks, but also tanks and helicopter gunships. No one expected an attack, but the enemy suddenly did just that nonetheless, and that adversary is very strong.

To ensure security, you must quickly build your defensive structures using machine guns, rocket launchers and even a flamethrower. Those complexes must be prepared for incoming ground and air attack, for multiple sides. You earn resources from killing enemies and can use that to upgrade your weapons.
