There goes any hope for trench coat turtles
Teenage Mutant Ninja Turtles: Shredder’s Revenge hasn’t released yet, but people are already speculating on whether there will be content released post-launch. When it comes to the specific idea of alternate costumes, the game’s narrative designer, Yannick Belzil, says that’s not something in the cards for now.
Belzil didn’t mince words about alternate costumes, saying that creating those costumes would take an immense amount of time. Each turtle moves differently and has their own animations, and creating a costume would include drawing out that costume for every single frame of animation. It simply too time-consuming of a project to tackle, and Belzil said it’s not a possibility.
That said, Belzil did say that if the team had the appropriate resources, they’d rather bring a new character to the game, rather than add in costumes for existing members of the roster.
You can hear Belzil talk all about TMNT: Shredder’s Revenge in an Xbox Expansion Pass interview. If you just want to hear the alternate costumes talk, you can find it at the 1:11:00 mark. Finally, you can see the full interview via the embed below.
