Does this game have replayability? Also how long is the length of the campaign?

Just like to know being that there is no online multiplayer.

Not a lot of replay value. There are two possible endings, but it's not that hard to follow a path that lets you pick which one you want at the end and either way you're not missing much if you don't see the other ending.

If you enjoy playing an above average shooter with a decent story, then there is replay value. Especially with the Ranger modes, ramps up the difficulty quite a bit.
