Master Rinzler

Master Rinzler can be obtained by reaching 60 stars in the Liberation campaign, or by trading in 75 Turret Blueprints. These in turn can be obtained by trading in Arachnophobia (Black Widow mech. brigade) or Spider Exterminator (Spider mech. brigade) convoy tokens, at the rate of 3 tokens for 1 blueprint, or at the Catacombs shop at the price of 42 diary pages for 5 blueprints.

On the battlefield, Rinzler uses a pistol with decent range but a rather low rate of fire. His main mode of attack, though, is by dropping turrets, which are somewhat more powerful than regular turrets; with the "Chief engineer" skin, he will sometimes also drop a Modernized Turret. These are extremely effective, especially against lower-level troops.
