Scorched 3D Portable

License: Open Source/GPL

Description: A straightforward yet very addictive shooting game you can play against "bots" or other people. Players control tanks which are scattered around a map. You choose a power, angle, and direction for your missile(taking into account the wind and the terrain you are on) and then shoot. You can buy enhanced weapons/defensive items with cash you earn based on your kills/damage inflicted on other players in the previous round(s).
