Is this game like Perfect dark?

I'm so tempted to sell my shi&*ty CSGO skins to buy this game.

Not at all similar, but get it anyways because this is the best game of all time.

They're superficially similar. Perfect Dark is more of a tactical shooter / puzzle game though, whereas Deus Ex is more of an action RPG / boy scout simulator.

Deus Ex gives you a lot of control over who you are, how you want to play, what you can do, and how you want to solve problems. The game also tries to accommodate for what you want to do, and what you might try to do. It's generally okay to fail missions, ignore secondary objectives, go against your orders, say the wrong thing, and poke at the world; there's a lot of optional / hidden content in the game.

Deus Ex is considered to be one of the greatest games of all time. That should be enough of a recommendation to get you playing. In fact, I think even Human Revolution failed to match it and it was a pretty good prequel.

As someone who has played a billion hours of both, they're definitely both similar in tone and graphics, and both suceed very effectively at capturing that 90s/X-Filesey aura of conspiracy and intrigue.

Deus Ex's gameplay and upgrade system is a lot more interesting than anything in Perfect Dark, but way less tight - it's almost an open world sort of game where you can approach obstacles in a lot of different ways, but you can be very messy while doing it.

Both have a nice variety of different maps and environments, but Deus Ex doesn't really have the tight level design that allowed for the timed challenges/optimisation available in Perfect Dark. In compensation, you're a lot more free to explore the world and just mess around and find hidden things - try to imagine a sort of combination between the Chicago level and opening Carrington institute level from P.D. , and add a whole bunch of dudes you can actually interact with and a much more complicated inventory system and you've got a pretty basic idea of how the game works.
