Heya! so there is this game i used to play on PS1, it was basically a simple gun game where u had one character or two (if u were playing multiplayer) and u would just move from left towards the right, shooting all enemies that would come in your way. There would be a boss battle at the end of each level and then after defeating him you would continue to the next level. Along the way you could get in a helicopter or tank and also get different guns along the way. Really wanna buy that game but can't remember the namecan anyone help me?
