Deus Ex: Breach was originally released as a part of Deus Ex: Mankind Divided as a sort of "arcade" take on the standard gameplay, but with today's Steam release it has become a standalone free-to-play game. Unlike Mankind Divided, each mission in Breach is self-contained and brings with it simple objectives which range from retrieving a set amount of information to defeating a specific enemy. And if you want to brag to your friends you can always attempt to reach the high score on specific maps, or try your hand at some of the custom challenges.
If you're wondering what all of this might look like, allow me to share with you the fairly lengthy preview trailer. Its a bit outdated by this point, but it should still give you a good idea of what to expect from Deus Ex: Breach. Anyway, have a look:
While I didn't really give Breach a fair shake, what little I've played didn't leave me very impressed. Then again, I do mostly play Deus Ex games for their story and RPG mechanics, so a game mode with all of that stripped out was never really going to appeal to me anyway. So if you're someone that doesn't mind all of that missing, you can find out more about Deus Ex: Breach by heading over to the official FAQ.
And on a slight side note, if you own a VR device you'll be glad to hear that the Deus Ex: Mankind Divided - VR Experience has now been released for free on Steam. Its basically a walking tour of Mankind Divided's most iconic locations, as well as a chance to view the world and its NPCs from a completely unique angle. Its only a demo so its not going to last you very long, but it is completely free, so its still probably worth checking out. Enjoy!
