Braniac was a tough nut to crack... this was probably my third attempt or so... I wasn't sure if we were gonna go with the skinny (more Terminator) version of Braniac, or the green-skinned one.... I think this version made it to the demos at SDCC, but I think the final version in the game ended up being much more "Gears of War-ish" .... I was purposely trying to keep Braniac streamlined and elegant, almost with a sense of 60's tech to it, BUT that can sometimes 'read' as simple on games nowadays, so I totally understand why Braniac needed to be a little 'busier' design-wise, specially as a "Boss character".
... although, I gotta admit, sometimes I do get sick of designs with 20 different patterns and shapes on just a forearm alone in some of today's game design...... it's a fine line between 'eye candy' and 'eye death-by-sugar'.
