The template includes a system for character movement, character interaction with different objects, use of various firearms, picking up and crafting different items, use of means of transportation, making of different enemy AI, etc.
All information about the project is in the documentation.
Also I recommend to look at these large packages with a large number of animations:
Close Combat: Fighter The combat system contains more of an animation of hand-to-hand combat.
Close Combat: Swordsman The combat system contains more of the animations with the sword.
In the 3rd update, close combat was added. You can add attack animations and fatalities from these packages.
