This was a University Team Project.
The game isn't pretty but the main focus was making a multiplayer game where up to 4 players can play together and if there are not enough human players than AI would replace the remaining players.
Human players can plug in a controller to play together ( e.g. compatible PC Xbox 360 controller ).
Demolition League is a 3D Multiplayer Driving Arena Shooter where 2-4 players fight in a dangerous arena containing NPC Monsters and Traps. The capacity of the game can be set as wished (2-4 slots) and human players are replaced by AI players if need be.
