The BETA assault from Minsk is worse than expected, with 200,000 BETA headed towards Fort Seelow, where the army will make its final stand to protect Berlin. With doubts about Lise growing in the squad, Theodor asserts her innocence to Irisdina, and acknowledges he has begun a sexual relationship with Lise, his adoptive sister, in order to keep an eye on her. The BETA overwhelm artillery forces with the Heavy Laser-class, and the 666th is sent to engage them.
