Treyarch is not about to ruin a good game by giving out subtle game modes. In fact, "Call of Duty: Black Ops 3" is about to become even more challenging because of its "Realistic" difficulty mode.

According to IGN, a list of trophies for "Call of Duty: Black Ops 3" revealed the difficult mode. A trophy under the said mode was even called "No One Will Believe You," which is awarded to players who can beat the shooter. In all of "Call of Duty" series, the Veteran is, by far, the hardest of its modes. However, this time, "Realistic" takes on that position.

The other game modes that accompany "Realistic" include Recruit, Regular and Hardened. Apart from the new challenging modes, the co-op feature of "Call of Duty: Black Ops 3" was even made more interesting. The "Realistic" mode, however, doesn't have a campaign for Xbox 360 and PlayStation 3, making it unavailable for those two platforms. Several trophies fall under the category of the Campaign Trophies, Zombies Mode Trophies and Multi-Player Trophies, reports Game Rant.

Be warned that the featured trophies may also contain some spoilers on the game's difficult mode and challenges, but just the same, they're listed as one of the trophies for the game.

As featured on Exophase, "Call of Duty: Black Ops 3" lists all the trophies for the game including Platinum, Disavowed, A Second Chance, High Tide, Belly of the Beast and many more.

Treyarch, on the other hand, still needs to give more details about "Realistic" mode in order for players to get the maximum gaming experience. For the multiplayer option, according to GameSpot, the maximum level that can be reached is 55.

Xbox Achievements dubbed the "Call of Duty: Black Ops 3" as the franchise's most ambitious project yet. With the help and contribution of Mark Lamia, the studio's head and the rest of the Treyarch team, the trailer reveals more of its secret and difficult game concept.

The new trailer has already been released ahead of its launching on Nov. 6. The trophies revealed can be unlocked through its single player mode while some can be achieved via the online modes. The trailer will fully dictate you the concept on how the story was made and appeal to players.
