First Person Shooter 3D

I made this game to learn the mechanics of "First Person Shooter 3D"  where the player must eliminate all targets to complete the game. This game is themed on a titan disaster where the player is a soldier assigned to kill all the titans in the city. 

In this game, players can shoot titans and kill all titans to win the match. if the player manages to finish off all the titans without getting attack, a UI will appear in the form of a dialogue that all titans have been defeated, and the mission successful, which indicates the player has won the match. but if the player is hit by an attack, the blood will decrease and if the player's blood runs out then the mission will fail and the player can repeat the mission or return to the main menu. 

Players can also run out of bullets if using weapons continuously, if bullets runs out, the player is required to look for bullet items scattered on the map in order to continue game.
