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.
