Deus Ex Hardcore Revival is a mod for Deus Ex Human Revolution Director's Cuts. The aim of this mod is to make the gameplay more balanced, since IMHO the game was inciting the player to play too much in a certain way. Last Version 1.020
The 10mm Zenith pistol with the armor piercing upgrade, the silencer and the laser rifle was too powerful, making the gameplay unbalanced, so to fix this... the 10mm pistol exist in 2 versions : A normal version which is compatible with the silencer and the laser sight and an Elite version (like in Mankind Divided) which can only equip the armor piercing upgrade.
The normal upgrades which the 2 firearms can equip is also different.
where the hell do you get this thing anyway?
In the mod, you can buy this gun from the Alice Garden Pods merchant during the first visit of Hengsha.
