3D game cinematic cutscene 20 sec

We need some cutscenes for our game project. Short videos from 15-20 seconds introducing our monsters, weapons, challenging themselves, shooting, and more... We would need the animations, level dressing, set up scenes, etc... For reference, we provide: 

• 3D models
• Map level
• Some other assets

Various monsters fire their weapons in a defensive position or run against other enemy monsters. Examples:

Several monsters in two teams shooting each other in a war zone with explosions/bombs and parts of the scenery being destroyed by guns and gunfire. One or two monsters walking calmly with their weapons and suddenly they find a horde of other monsters that shoot them and they have to run to flee and when they flee they find themselves face to face with zombies that also shoot them
