Would the name “Hallowed” receive protection as a trademark or as trade dress?

Two computer science majors, Trent and Xavier, have an idea for a new video game, which they propose to call “Hallowed.” They form a business and begin developing their idea. Several months later, Trent and Xavier run into a problem with their design and consult with a friend, Brad, who is an expert in designing computer source codes. After the software is completed but before Hallowed is marketed, a video game called “Halo 2” is released for both the Xbox and Game Cube systems. Halo 2 uses source codes similar to those of Hallowed and imitates Hallowed’s overall look and feel, although not all the features are alike. Using the information presented in the chapter, answer the above question.
