Welcome to The Testing Room where three of the gaming industry’s best consultants (to never consult on a game) bring fun new topics each week to talk, debate, and/or laugh about. This week is our titular 69th episode (very noice!), where we talk about underrated game mechanics that weren't used again or at least not often. Some examples are the Dead Space navigation system or maybe even 3D on rail shooters.  Listen in and let us know your own opinion and what mechanics we have missed. Don't forget to send comments and questions to [email protected].
