The Trophy System excels in objective-based game modes such as Domination or Demolition, although mostly in Drop Zone due to excessive explosive weaponry and explosive based pointstreaks. The Trophy System can protect a player while they attempt to secure the objective. Most enemies bombard objectives with explosives and other projectiles to attack them, and the Trophy System will guard against this with great effect.
The Trophy System is most effective when positioned in front of the player while in the prone position. This allows most projectiles to be destroyed without damaging the player. Interestingly, enemies may (rarely) end up getting killed by the trophy system when friendly tactical equipment and grenades are thrown adjacent to them and get destroyed.
The Trophy System appears in Call of Duty: Black Ops II. Like its Call of Duty: Modern Warfare 3 counterpart, it can destroy two projectiles at a time before destroying itself. But unlike in Call of Duty: Modern Warfare 3, it can be tossed ahead of the player, in case there may be projectiles incoming in front of them. The Trophy System can intercept a wide range of enemy projectiles, including all lethals, all tacticals (even other Trophy Systems), Rocket Launcher missiles and Grenade Launcher grenades, and various scorestreaks. Players will receive 25 score towards their scorestreak for every projectile destroyed with the Trophy System.
The Trophy System returns in Call of Duty: Ghosts's multiplayer. It is also available in Extinction mode (where it is simply called "Trophy"), where it destroys the Gas Clouds attack from Scorpions, and it will not be attacked by Aliens.
Unlike its Call of Duty: Modern Warfare 3 counterpart, the Trophy System can be thrown instead of being directly placed on the ground.
The Trophy System can destroy equipment that has been already been placed on the ground. For example, if there is a Claymore on the ground, then a player throws the Trophy System near it, the Claymore will be destroyed by the Trophy System. This works for many other pieces of equipment, such as Bouncing Betties, Tactical Insertions, Shock Charges, etc.
When the Trophy System has destroyed one projectile, it can normally only destroy one more (limit of two), but if the player picks it up, and places the same Trophy System down, that Trophy System will be fresh and can destroy 2 projectiles again. This can be repeated as many times as possible.
The Trophy System has a note that says: "Jack in the box".
The Trophy System will destroy a semtex grenade stuck to a player.
The Trophy System will even destroy other thrown Trophy Systems.
Unlike in Call of Duty: Modern Warfare 3, Trophy Systems in Call of Duty: Black Ops II will destroy Combat Axes.
The Trophy System uses the S12's firing sound when destroying something.
The Trophy System will kill enemies who place a Tactical Insertion within it's range.
Destroying a Hellstorm Missile or Hunter Killer with the Trophy System will not give the user the "Intercepted" or "Rejected" medals respectively.
The Trophy System will also destroy fired Ballistic Knives and occasionally Crossbow bolts.
