The skull bot is a small scouting robot I've been developing for the good Dr Steel  toysoldiersunite

As you can see this model is slightly different from my previous skull bots

This one is an offensive model.

The assassin drone is a very versatile machine

It's main weapon is a modular one shot 10mm cannon. This is it's main means of assassination and can be loaded with several types of ammunition depending on the mission parameters. Ranging from a high explosive micro missile, or a 9mm slug or a poison gas canister or even a suicide explosive charge.

Surrounding the main cannon are 12 smaller weapons barrels. These secondary weapons are stealth support devices. The use compressed air to fire a variety of projectiles, ranging from tranq or poison darts as well as tracking devices. If you don't want to leave even the small amount of evidence of a dart in the neck the bots can also be equipped to fire capsules that will dissolve in food or drink sedating or killing the diner.

After the assassin ot has completed a mission it will scuttle off to some out of the way location and activate it's self destruct protocol. a powerful acid will be released dissolving fragile circuit boards and a number of structural components leaving a small puddle of melted plastic and metal
