In Modern Warfare Remastered, we get the opportunity to redeploy on classic missions alongside Soap MacTavish, Captain Price, and more familiar faces. Thanks to the benefit of hindsight, we can use our knowledge of the events that take place in Modern Warfare 2 and 3 in order to change the future and create a time paradox - and pick up a hidden Trophy or Achievement in the process.
During the 'One Shot, One Kill' mission, you attempt to assassinate ultranationalist leader Imran Zakhaev using a long range Barrett M82 sniper rifle, but there is also another important figure in the background of this scene. In the front seat of the vehicle parked on the far left is Vladimir Makarov, one of Zakhaev's lieutenants, who will go on to lead the ultranationalist's terror attacks in the two Modern Warfare sequels.
If you take him out here you could stop all of that from happening, as well as earning the Time Paradox hidden Trophy or Achievement for your collection. Here's how you get it:
Keep an eye on Zakhaev as he completes his deal.
Move over to the back left vehicle to spot Makarov in the front seat.
When the time is right, take your shot on Zakhaev then immediately aim at the rear left vehicle.
Pump a few rounds into the front seat to eliminate Makarov, changing the future and collecting the Time Paradox award in the process. Good night!
