There are some shooters with gimmicks this seventh console generation and the sixth, which ones are your favorite if any? I personally like the one in Timeshift the most with Borderlands being 2nd but that game doesn't really count.
a gimmick is a unique or quirky special feature that makes something "stand out" from its contemporaries. However, the special feature is typically thought to be of little relevance or use. Thus, a gimmick is a special feature for the sake of having a special feature.
