More outlying human colonies have fallen to Swarm attacks this month, the most notable of which being the research base of Tau Ceti 5. This base was known for its intensive research on the alien threat, having produced a number of papers on their behaviour and biological makeup, information the ISAF paid a great deal for. It's unknown whether the attack on this base was caused by the recent presence of a number of recently captured live bugs or whether it was just a random attack.
