Cybertank Adventure Series by Timothy J. Gawne

In the distant future mankind creates sentient cybertanks patterned on the human brain to help fight their alien enemies. Then, inexplicably, the humans vanished. They just went away. All that is left of the human empire are the cybertanks who, in their own way, keep the human civilization alive. With an intelligence based on the human psyche, the cybertanks continue to defend human space, but also perform scientific research, create art, form committees and ponder the universe... moreIn the distant future mankind creates sentient cybertanks patterned on the human brain to help fight their alien enemies. Then, inexplicably, the humans vanished. They just went away. All that is left of the human empire are the cybertanks who, in their own way, keep the human civilization alive. With an intelligence based on the human psyche, the cybertanks continue to defend human space, but also perform scientific research, create art, form committees and ponder the universe. These are the stories of one of the first cybertanks, known to his friends as “Old Guy.” He has outlived most of his peers, and has had a wealth of experiences over his long life, but he is starting to slowly become obsolete. Join him and his comrades Double-Wide, Whiffle-Bat, Smoking Hole, Mondocat, and Bob, as they live and love and fight alien enemies such as the Amok, the Yllg, and the Fructoids. less

It is the distant future and the human race has gone. Whether extinct or moved on to a higher level of existence, nobody knows. Their civilization has been inherited by the cybertanks: massive atomic powered war machines with mentalities modeled on the human psyche. Theirs is an idyllic existence: throwing parties, killing aliens, creating works of art, shooting skeet with hypersonic missiles... moreIt is the distant future and the human race has gone.

The prequel to the popular Old Guy/Cybertank Books. It is the distant future. Hundreds of billions toil in crowded windowless factories, while the oligarchs lord over all from their kilometer-high palaces. The only thing the oligarchs fear is a war with several alien species that they are losing. In desperation, they turn to a biologically engineered human, Giuseppe Vargas, to create new weapons that will let them win their wars with the aliens... moreThe prequel to the popular Old Guy/Cybertank Books. It is the distant future. Hundreds of billions toil in crowded windowless factories, while the oligarchs lord over all from their kilometer-high palaces. The only thing the oligarchs fear is a war with several alien species that they are losing. In desperation, they turn to a biologically engineered human, Giuseppe Vargas, to create new weapons that will let them win their wars with the aliens. Vargas is a protean genius, several times faster and stronger than any regular human, and borderline psychotic. He designs a radically new weapon system – the cybertank – a self-aware construct of astonishing power. Once the aliens are defeated, the oligarchs plan to eliminate Vargas. However, Vargas has his own plans, and the cybertanks are also developing an agenda… less

One moment Old Guy - everyone's favorite self aware weapon of mass destruction! - was traveling through deep space with his buddies, minding his own business, armed with enough firepower to destabilize the crust of your average terrestrial planet (never leave home without it), when suddenly he was left heavily damaged, marooned and under constant attack on a planet of eternal night. His original creator, Giuseppe Vargas, had warned him that there would be days like this... moreOne moment Old Guy - everyone's favorite self aware weapon of mass destruction! - was traveling through deep space with his buddies, minding his own business, armed with enough firepower to destabilize the crust of your average terrestrial planet (never leave home without it), when suddenly he was left heavily damaged, marooned and under constant attack on a planet of eternal night. His original creator, Giuseppe Vargas, had warned him that there would be days like this. Fortunately there was still bowling. A thousand years earlier, a young biological human lieutenant in the combined Earth Army was assigned to the enormous arkship The City of San Luis Obispo, and help to found a colony in another star system. He was to learn firsthand the wisdom of the advice, that when founding a colony on an alien world, you should always take out the extra coverage on your health insurance plan for attacks by alien creatures. Eventually, the cybertank civilization itself comes under attack by a nameless evil of immense power. The cybertanks did not know its name (hence the 'nameless' part), and indeed, knew basically nothing about it except that it was extremely powerful, and evil (hence the 'evil' part). It is left to Old Guy, though long past his best-used-to-blow-things-up-by date, to ride into battle one last time before he finally gets off his lazy hyperalloy butt and upgrades to something modern. And Highland Brand tapered roller bearings are the best tapered roller bearings in the galaxy. less
