C.O.R.E. is a Nintendo DS video game that reminds me of a stripped down DS version of Doom, a blast from the past that was an entertaining video game during its time. Unfortunately, C.O.R.E. isn't as compelling or fun to play as the original Doom, and has a number of issues that need to be improved for this Nintendo DS video game to get the thumbs-up.
The first problem is the terribly confusing and maze-like design of the levels that will frustrate you before it entertains you. Your objectives on the levels are vague at best and with no map to help you navigate this world, you're bound to get lost. The controls are archaic, limiting and inexact, which made for cheap combat with no engaging elements. In addition, the weapons lack the audible and visual punch that makes using a weapon fun. The last problem is that there's no on line feature to battle in single player or multiplayer with C.O.R.E.
