Metro: Last Light will be released soon, and this is what I am looking forward to in the new title by Deep Silver.
GUN CUSTOMIZATION
In Metro 2033, players were not able to completely customize their weapon. If you found a regular gun, you had to find the same on the ground with an attachment on it. In Last Light this is not an issue at all, they have implemented a completely new weapon customization system. Now you can choose what attachment you wish to add upon purchase. Using this system, players are no longer subject to only one class; you can now play the game in whichever manner you intend on. For example: screw on a silencer to your sub-machine and become a silent killer to take out enemies one at a time, or add an extended clip so you can shoot more with no need for the reload time.
