Was it Metal Slug? It was Neo Geo, but I had it on PC as well.Cameron Wang said:Created an Escapist account for this exact reason. I remember playing this for countless hours as a child, on a Windows 95, I believe.
The game was a side scrolling game where you are a gunman going around and rescuing people (not the actual idea of the game). First level takes place in a city-scape environment and there are people trapped which you rescue. As the game progresses, you may have gotten upgrades for your gun that will last as long as you have bullets for that weapon. After that, I don't remember much except for the final boss, which is some kind of evil doctor inside a laboratory. Sorry if there isn't too much detail.
As for the graphics of the game, its a fairly pixelated game with some good detail. It's like Chrono Trigger styled. Please keep in mind that the game ISN'T about saving people rather defeating this evil doctor. Another thing I just remembered while writing this post is that there is a enemy in the game that is black (kind of like the monster in AVP) that shoots short blue lasers. If you manage to kill him, you acquire the ammo until you run out, which you then revert back to your original weapon.
I'm pretty sure that I didn't need a CD to install this game. Definitely a PC game and not a console game, unless it was remade for the console, but I doubt that. If you can find this game, I will send 10 USD via PayPal to you, just as a thank you for finding a large piece of my childhood.
