The assaultron robot was constructed by RobCo and sold to the US Military and the as a front-line wartime combatant, and to the The Whitespring Resort as security robots. It is fast and deadly at close range, and employs a devastating laser at a distance. The dominator variant can also use stealth technology.
The assaultron's body bears some striking resemblance to a female figure, coincidental or not, with prominent hips and chest, the latter appearing to house additional servos for the robot's arms, hinting at their strength in melee combat.
An assaultron's head houses an incredibly powerful laser that requires charging up before being fired. The assaultron's face will become surrounded with red electric energy when it is charging its laser beam attack, after which a great laser burst will be unleashed, doing serious damage to anyone who is caught in it.
Assaultrons' weak points are their legs. However, when these are destroyed, the assaultrons will continue to pursue the target by crawling on the ground. After taking sufficient damage, they will charge a potentially deadly explosion as a last desperate attempt to eliminate the target. Killing them before they can activate it will result in a normal death.
On lower levels they can be very difficult to face head-on, due to their fast speed and powerful attacks. A low-level player character may have difficulties killing or crippling the assaultron before it's able to get into melee range, or charge its lethal laser attack.
