Hack all the turrets you can, to get them on your side against other foes, but be careful to disable the security system first.
The Blast Turrets have a light brown steel armour. They have the same amount of hit points as all other turrets. The explosions deal a high amount of damage and what's worse, have a treacherous splash damage: standing in their radius always means full damage, no matter the distance! It's best to move swiftly to avoid these explosions. They are equipped with a mounted rocket launcher that fires accurately, but at a slow rate. The CRU-22 Blast Turrets (also known as Rocket Turrets) are the most advanced type of all standard Turrets.
