Free HD Games on your Browser

Looks like something an ad might say but hey free games? A friend posted this on facebook and it caught my eye. The website is called Core Online. Click Here to check out their website. Right now on their front page they're featuring Hitman: Blood Money, Mini Ninjas and 2 Tomb Raider games, Underworld and the Guardian of Light. Seems like you only have a certain amount of playtime. I didn't have time to try it out but hey free is free, right?
