While not everyone finds the idea of watching other people play games entertaining, it can be quite an informative way to find out about the game, since you're seeing it in action, unadulterated or tweaked and free from after effects aesthetics changes.
So if you're interested in the upcoming Deus Ex: Mankind Divided game, maybe these 25 minutes of it will get you even more excited, or make you think otherwise.
Adam Jensen is back with a new suite of abilities, tools and skills. However for the purpose of the demo he is a little more powerful than usual, having a full suite of life, energy and ammunition. Presumably because Square didn't want the person showing the game off to accidentally die and ruin the demonstration.
While this is video from an Alpha build, so should not necessarily be considered indicative of what the final game will be like exactly, it does at least give us a good idea of what the game will look and feel like.
For added details, listen to the commentary track from the game's executive audio director ,Steve Szczepkowski. As he explains, while Jensen is on an important mission, he will soon begin to question whether those ordering him around are in-fact the ones who should be looked into.
