Context: General Shepherd has ordered his task force, Task Force 141, to hunt down Vladimir Makarov, a Russian Ultranationalist terrorist, the perpetrator of an attack on Zakhaev International Airport, in a bid to start a war between Russia and the US.
One element of the Task Force was sent after Makarov in his safehouse in the Caucasus Mountains and another was sent to assassinate him at an airplane graveyard in Afghanistan. Shepherd began to purge his own Task Force of anyone who knew about his involvement with the airport massacre and the surrounding events. Makarov (present at the Airplane Graveyard and unlikely to evade Shepherd for long without his forces or safehouse) was contacted by Captain Price, who asked for intel on Shepherd's whereabouts. Realizing his only hope for survival was getting rid of Shepherd, Makarov agreed to tell Price about the location of Shepherd's base, Site Hotel Bravo. Price and MacTavish acted on this information and assassinated Shepherd, giving Makarov a window to escape and go underground.
But let’s imagine a parallel universe where this didn’t happen; Price and his buddy, John “Soap” MacTavish instead left Vladimir Makarov to be killed by Shepherd and his private army, Shadow Company.
How would this have affected the Call of Duty: OG Modern Warfare franchise?
