Same subgenre of shooters as FEAR. The gunplay doesn't feel as good as FEAR though, but it somewhat makes up for that with the time manipulation aspect. Timeshift also makes excellent use of time travel, as it is effectively necessary to use it in combat to avoid dying. It's definitely worth a playthrough, but wasn't interesting enough to make me wanna replay it. If you can get it for like $5 or $10, it's a decent shooter with a decent setting.
