So far, we only know that Cyberpunk 2077 will feature crafting and weapon upgrades. This means that by exploring the world, we can collect items that would help us expand our equipment.
Some weapons can be upgraded so that they do not kill, but simply stun your opponents. Thanks to this, you can complete the game without killing any enemy.
As for the weapons, you can add a silencer or a sight. An interesting solution is the ability to change the type of pistol to start firing thermite rounds.
