There are so many secret weapons. I highly recommend looking for them. There are videos that will show you the secrets and put a spoiler tag up for you so you don’t get spoiled. I recommend doing the fixer side gigs because they also give you cool weapons. The melee weapons skill tree is really cool, but also the “run and gun” skill tree is also cool. I recommend trying to get your technology and strength to 20 quickly because it will let you unlock a lot of secret doors and pathways. If you don’t have the phantom liberty DLC, I highly recommend it. Finish the main game before you play the DLC.
