HOME

Metal Thunder 2 ;

We controlling maybe 9 different Axis and Allied tanks.Axis Unit tanks are Panther,Panzer IV,Tiger tank and other german armored cars...Allied tanks have Britsh and American tanks.They are Sherman,Crocodile,Churchill and other armored cars.Man your tank as you blast all the enemies. Lots of buildings and barricades to destroy.

The project is developed using Gml. I have used Game Maker Engine for this project. You can see the sample code below.

Development Time : 6 month(02/2012 - 08/2012)
