Malice@Doll

If you like the dark atmosphere from Texhnolyze or Malice@Doll you will probably like both of them. However Malice@Doll may not be good as Texhnolyze. 

Nightmarish CGI ventures (for better and for worse) about alternative apocalypses befalling mankind, both find themselves experimenting with strange structure and pacing 

Insects and body horror applied to a primarily female cast of characters. Both are fully computer generated and have a similar dark, semi-surreal atmosphere. Bacterial Contamination has more modern and competent visuals, while Malice@Doll offers an actual storyline. 

Both have a very creepy and other-worldly aura to them and are animated to look like a puppet play with dolls. If you like one, you'll probably like the other. 

Forward thinking experiments in animation and visual storytelling made by auteurs in the anime medium 

2000's OVA series with a dark, surreal atmosphere and strong horror visuals. 

Both animes show us some creepy images and are quite hard to watch. None of them are -good-, but both share similar atmoshphere of disturbance and discomfort. 

Both are badly 'animated' but cover the existentialism of machines and love. 

Both of them are about an unlikely protagonist going against supernatural beings, with a creepy/surreal art style. 

Early-2000's horror CGI anime with a dream-like and somewhat liminal aesthetic. Focus around a gloom futuristic world that feels empty, with various scenes made for you to question the reality of it. Interesting graphic horror designs and questions about identity with their respective protagonists.
