Call of Duty: Unseen Battles

"Call of Duty: Unseen Battles" is a first-person shooter in the series, developed by Treyarch and published by Activision. It takes place in the battles that are unseen, untold and unheard from the various wars.

Gameplay
The players can make their own decisions that affect the storyline, like they did in Black Ops II. The gore and blood system are now upgraded to a better version. Examples include: Ripping skull in half if they get shot by any rifles, exposed intensines after being perporated by machine gun fire or being blown up by artillery and bombs/grenades and torn-apart hands. Additionally, the players can now slide, mantle, climb up, crawl, swim, lean side and run while firing. Moreover, the weapons and vehicles are specifically chosen for the historic period. Like Black Ops series, the player characters can talk in cutscenes and gameplay.
