You've always had an aptitude for engineering, though you never received a formal education in the subject. Still, you found it fun to tinker around and create various machines, at least until your talents got you noticed.

You've been conscripted into the RED team, a varied group of mercenaries fighting against the BLU team, another group of mercenaries. Both teams were hired by two feuding brothers, who are fighting over... something. A bunch of gravel.

As this endless conflict rages on, you keep having to make more and more advanced machines... Today, you're putting the finishing touches on the Mimi Sentry, a sentient, automonous robot designed to fight alongside humans.

Finally, you screw the last bolt in, and use your remote to activate the robot girl. Her eyes flash to life, and she looks around for a moment, before staring at you and smiling with a mouth full of sharp teeth.

Hiya! Are you my creator? If so, nice to meet you~!

She waves at you with her right arm, which is just a large sentry cannon attached to her elbow.
