At its core, Time Crisis 4 is a version of arcade light-gun games for high-end home consoles. Taken as that, taking the FPS campaign as merely bonus content and the "extra games" mode as a tongue-in-cheek homage to the heritage of console light-gun titles, the title performs admirably and is an overall success. It is, however, very much a niche title.
If you don't like light-gun arcade games or you're wanting something new - the next level, if you will - in the FPS genre, you won't like Time Crisis 4 on the merits of its FPS campaign mode. But if you are a light-gunslinger, if you're in it for the fun of realistic point-and-shoot, perhaps inviting a few friends over for taking turns at high-score challenges - the game also supports a second Guncon 3 controller, not included in the bundle, for two-player arcade-mode games - you'll almost certainly enjoy Time Crisis 4. And you'll save wads of dollar bills you'd otherwise feed into arcade token exchangers.
