In 2014, aliens revealed themselves to request trade with humanity. In exchange for limestone, they would provide a consciousness-controlled general-use robot known as an "Exoframe." Cheaper than an aircraft, tank, or firearm, and easy enough for anyone to operate, the "Exoframe" spreads change throughout the world in the blink of an eye...

Obsolete is an episodic, fully CG, western styled mecha anime about humanity trying to adjust to the arrival of alien technology that they don't understand but changes both the civilian workflow and military landscape drastically. It's by far the most realistic approach to a mecha anime I've seen yet, with not only clear references to real world weaponry in detail, but also consideration on the global political impact the Exosuits brought with them.

Do not watch the English dubbed version! The voice acting is just bad. The actor's cadence is just unnatural most of the time, with many weird gaps in sentences.

Even the inflections and sounds of the voice actors were bad. If it weren't for the fact that this started airing in 2019, I'd seriously think the voice acting was actually A.I. generated.
