Call of Duty Black Ops 3 is clearly set for release as an ingenious cryptic trailer teases fans. The short video not only announce an apparent Black ops 3 title but reveals  subtle sneak peeks to possible game content, which is not apparent at the first time one views the teaser.

Possible In-game locations

Included in this one-minute trailer are sets of coordinates that point out to real life locations on the map. The locations are as follows as detailed by Gamespot.

• 1.300 N, 103.8000 E - this points to an elementary school in Singapore.

• 30.0500 N, 31.2333 E - This is a place near the Nile River in Egypt.

• 47.3667 N, 8.5500 E - This points to a place called 'Gefängnis Zürich' literally translates to Zurich-Prison.

The gameplay may include these locations as an integral part of this Black Ops 3 story, especially as fans would expect these references to appear in the game. A prison, a Middle Eastern setting and a South East Asian destination maybe locations for big game events in this apparent sequel.

Possible return of familiar faces

As previous Black Ops titles explored time-travel and alternate history, one possible plot ingredient is 'revisit" sequences to previous events in BO1 and BO2. It may be also be a hint of an interweaving of the three titles, giving that "aha" moment to players when seeing BO1 or BO2 events in another perspective. This is a genius move, if done perfectly, to prompt players to revive their BO1 and BO2 experience again.

Finally, the epic references to another zombie mode

IGN posted information that apparently confirms the addition of 'zombie' mode in Black Ops 3. The said info was extracted from the Call of Duty webpage. This is the full source code text shown by IGN.

"Black Ops 3 is the first title for next-gen hardware in the critically acclaimed Black Ops series.
