What would DOOM Eternal be without the ability to carry the arsenal of an entire squad of super-soldiers in the pockets of the Praetor suit? It takes the right tools kill in an enjoyable way. Here's all the information about the weapons.
You should know that they are all obtained within the framework of the story, and that outside of Unmaykr, it's impossible to miss a weapon.
Weapon Mods
As in the 2016 instalment of DOOM, you will be able to install two mods on the majority of weapons, and switch from one to the other as needed. These modifications can be chosen from a list after finding this edition's version of the delivery bots.
Modifications usually add a special secondary firing mode to a weapon. This can be a more powerful shot, or something entirely different, such as a grapple. Modifications have 2-3 upgrades that can be applied with weapon upgrade points, then a very powerful third (or fourth) upgrade that requires you to complete a particular challenge with that weapon once the previous modifications have been unlocked.
Towards the end of the game, you will start to find mastery tokens that allow you not to skip the challenge, and unlock the ultimate modification directly.
Weapon Mods
As in DOOM [2016], you'll need these points to improve weapon mods, and there are several ways to obtain them.
The easiest way is to kill demons. You can get a certain number of points this way during each mission. Killing all demons will earn you a lot of points.
The second method is to discover secrets. This will earn you a point each time. Be sure to search every nook and cranny of the map if you want to improve your weapons as much as possible.
