Few days ago Runescape:Chronicle came out on Steam. I played the closed beta but when it came out my stats were wiped, but im getting back into it now. Glad it's having a really positive reception on Steam thou.
Ahh Mirrors Edge. I'm not sure if I pt it on my list but I guess it should be. It did have a few glaring issues thou, but I found it fun enough, but I only paid $2 for it anyway. The main issue was that platforming from a first person perspective becomes unpredictable and hard to control, but it didn't bother me too much. Looking forward to the sequel, but I wont be able to afford it for a long time.
The boss battle is really hard. I've only ever beaten it on easy. But you need something like a laser to break the shield and definitely a beam weapon to deal as much damage as possible because of the compact rooms.
