- There are currently at least 2 versions of Rig EK being used by different campaigns.
- One is an updated/evolving "VIP version" version of Rig EK that @kafeine has been calling RIG-v as described here.
- The other version of Rig EK is "regular Rig" that generally looks the same as it has for a while now.
- RIG-v is currently being used by the Afraidgate and pseudoDarkleech campaigns.
- Regular Rig EK is still used by the EITest campaign.
