Melee weapons are gone. (No shovel)
The in-game currency (yaran pesos) has no purpose after you buy or collect all the weapons and armor.
Ammo types are no longer selectable and are permanently attached to the weapon.
Can no longer kick enemies by looking down and using melee/takedown.
Human allies are gone.
Weapon attachments are made of trash.
Outfits are made of trash.
Outpost master is gone in favor of insurgency, but outposts can no longer be reset at will.
Esparanza is basically locked down and is a far cry from the vast expanse of urban combat we were promised.
DLC content is copy and paste.
Enemies are bullet sponges and they only share 2 or three skins meaning your killing the same guy a lot.
Weapon pickup is gone.
Looting animations are gone.
You have access to you're entire weapons catalogue at all times which makes no sense.
Theres no final battle. Anton was over hyped.
As a huge fan of this series I was extremely let down by this entry and just restarted 5.
