10 Video Games Only The Most Skilled Players Can Handle

2. Rainbow Six: Siege

It might have launched in a state more befitting an Alpha test, but R6: Siege has blossomed into quite possibly the most tactile FPS on the market.

Where Call of Duty focuses on reaction times and Battlefield playing the long game, Siege's mix of ability-equipped Operators and maps riddled with scores of insertion methods is in a league all its own. Destructible scenery means grabbing hostages or taking out opponents can be done from literally any angle, encouraging fortification and stealth takedowns as much as exploration or map learning.

The result is simply a shooter that exceeds in pure tactics; something that will have your expectations for breakfast first time round, but slowly lets you become the master over a considerable amount of time.
