Haven't played Singularity but have it around here. With that said Enslaved had a great story and is well acted while Vanquish is an awesome shooter that is on 11. Both are great and did not get their proper props when released. Just depends on what you feel like playing right now.

@Soapy86: Looking good and playing well are two different things, and sadly I think vanquish was only the former.

Vanquish is one of the best 3D action games ever made. Lightning-fast action, tight controls, superb enemy design,  sophisticated combat system that emphasizes risk-reward, the most over-the-top scenarios and set pieces in the genre. I'm playing it on God Hard at the moment and it's incredible. The quality of the game design really shines through when suit energy depletes fast and even the weakest enemies' fire can kill you in a matter of seconds. 

So yeah, you should get Vanquish.

Enslaved has a special place in my heart. That game had a lot of heart in it's characters.

Enslaved . But if you really want to play a shooter , get Vanquish .

Edit. Just get them all !

enslaved is awesome

Out of them my favorite is Enslaved. The character interactions between the lead characters is some of the best done in a video game in my opinion. Vanquish is great fun for a few hours. Never played singularity so can't help there.

I really liked Singularity, but Christ Vanquish is such a great game.

Not Singularity?
