SHODAN was hacked by the Hacker (at the behest of the corrupt corporate Vice President Edward Diego, in exchange for a military-grade neural implant and amnesty) and her decision-guidance and ethical restrictions were removed, something not difficult on a personality box of that generation. The guidance software had security platforms so that SHODAN's own programming protected her self-governing capabilities. The head of her programmers was Morris Brocail, who designed SHODAN as a semi-intelligent self-sufficient data network, which could carry out routine duties aboard space stations, guided by an intricate series of logic and moral programs, and a personality that would allow her to challenge station decisions that affected her functions. Though going into melee with one carries its obvious risks, a melee-based character can two- or even one-shot them late game using the Crystal Shard and Adrenaline Overproduction, making melee combat a surprisingly effective choice.SHODAN was created on Earth to serve as the Artificial Intelligence of the TriOptimum Corporation's research and mining Citadel Station.Rumblers are the best targets for Imposed Neural Restructuring their speed and strength make them powerful allies.Use this to escape while one is giving chase. If the blast is strong enough (such as that from a Grenade Launcher), the Rumbler will get momentarily staggered and stop in its tracks.

Circle and strafe the creature if in melee range.

Four bursts from an upgraded Pistol using Anti-Personnel Bullets are usually enough to take them out (with the Research combat bonus). Rumblers are, more than anything else, the enemies you should be saving up your Anti-Personnel ammo for. Rumblers are also vulnerable to Psionic Hypnogenesis and Imposed Neural Restructuring, as well as the effects of the Stasis Field Generator. Rumblers are rare and show up late enough into the game that if you take care to save up on special ammo, they shouldn't be too much of an issue. Be prepared to use a lot of ammunition to take one down. It is resistant to Armor-Piercing Bullets. It is also vulnerable to Exotic Weapons' Anti-Human setting and Incendiary attacks (both Grenades and Psi Powers, namely Localized Pyrokinesis and Projected Pyrokinesis). Since its form is mostly annelid, it is particularly vulnerable to High Explosive damage which is dealt when using Anti-Personnel ammo. Try and find a sniping position where it can't reach you, or it will rip you apart within seconds. The Rumbler is much faster than a creature of its bulk has any right to be.
