Yes it is confirmed that Borderlands 2 will have a Siren class like the original did. But, Maya who is the new Siren, will not have the “phasewalking” power as did Lilith. Gearbox states that all Sirens are connected, but they do not have the same powers as each other. So, it sounds like Gearbox is trying to elude to something bigger with the Sirens. What that will be? Only time will tell. Until then, enjoy this 14 minute gameplay of Borderlands 2…while it’s still available.
