Crash Commando is a side-scrolling deathmatch shooter updated for today’s console consumers. It (and many other games) take much of the gameplay from Worms, the hugely popular invertebrate killing simulator of 1995.
You take control of a generic soldier (red or blue) and choose from a selection of standard weapons such as rifles and grenades. The levels are predominantly 2D gameplay-wise, although the graphics are 3D and show things like other battles and scenery in the background.
This is an under-par game that gave me no incentive to keep playing. If only the game had a better variety of weapons, then I might have had better thoughts about it.
