Mass Effect 2: 10 Cut Characters You Never Knew About
2. The Tank
A concept tied to Legion, the Tank was a robot that Shepard would own and could be improved much like the Normandy SR-2 by buying upgrades to increase its effectiveness.
Bioware initially considered having the Tank be an illegal AI. It would hinder the player as they travelled around the Citadel, as AI was banned, especially after the events of Mass Effect.
The Tank would have introduced themes of slavery as Shepard would effectively own a sentient being. Tali’s interactions with an AI owned by Shepard would also be interesting, considering her species history with the Geth.
