Could it possibly be Decent or Decent 2?
Neiter are side scrollers but seem to match your description otherwise.

I'm a huge Killzone fan and even made a video hyping up KZSF but after seeing the multiplayer gameplay, I'm not stoked. They have taken the series and headed in the way wrong direction. Instead of building on the impressive Killzone foundation, we are getting what looks to be call of duty: Helghast edition.

I'll wait for a friend to get it and check it out before I dismis any thought of playing it but right now it's looking grim.

To be honest, everybody saying "this launch title sold me on a getting an xbox1" are just people who wanted to be impressed with the xbox1. I have a xbox360 and has been my primary console this generation but there is no reason to buy a xbox1 at launch. The titles are limp at best.

Ryse? I'm not trusting a former Kinnect title to be anything other than a crap shoot at best. It could be good but I'm not holding my breathe.

Forza? Let's be honest. It's going to be more of the same. Just like Drive club and GT on the playstation side.

Dead Rising? Where you really impressed with Dead Rising 2 or any of capcoms recent games for that matter? I haven't been, including the joke that capcom has the nerve to call Lost Planet 3.

After a failed DRM policy, still having to connect to the internet and this ignorant kinnect policy, plus a $100 more than the PS4 (which IGN reports developers already saying it's more powerful then the XB1)  I see no reason to buy a Xbox1 at launch.

The only game Microsoft showed off that had me interested is Titan Fall but I'll pick that up on PC. What hurts microsoft on that front though, is that it's becoming more and more likely that it is only going to be a timed exclusive, with the PS4 getting it down the road.

Microsoft slapped around Sony this generation. Heading into the next one it's looking like Sony is about to return the favor, especially since Microsofts best Developer has gone 3rd party.

Sadly, with GTA5 now out, this is only going to get worse.

And this is why people are worried about the Xbox one's connectivity crap.

Beyond 2 souls.

I'm enjoying it so far. With all of the different things to do in the game, it's hard to get tired of it really.

I'd go with more than a 12 gb ps3 seeing how every game you play has to be installed, as well the apps for Netflix and other streaming services as well. If you look around you can likely find some in a similair price range.

8 or 9. 

The dreamcast was one of my favorite systems ever and I really wish Sega would jump back into the console wars, especially since Nintendo is doing it's best effort to kill themselves.  

Megaman.....oh how i miss thee 

Forza is awesome but i mostly felt the need to reply because "In flames we trust"  \m/
