I.T. Kid

Final Fortress is YoudaGames' 2006 defence shooter. You take charge of the WTDX 4224, the last cannon on the wall, and the enemy comes at you in waves -- infantry first, then armour, then the machines that take several hits to bring down. The barrel follows the mouse and the left button fires.

Every kill pays, and the money is the game: between waves you spend it on the gun itself, on the shells it fires and on the ground around you, so the answer to a harder wave is a bigger cannon rather than a faster hand. The enemies, the buildings and the explosions are modelled in three dimensions, and the fortress holds only as long as you keep feeding it.

It is the earliest of YoudaGames' run of Flash action-strategy games, and the one that sets the pace its later titles -- Rail of War and Skies of War -- build on.
