Sorry,
They are action games with hack & slash gameplay.
Basically you have a battlefield filled with enemy and ally solders (most of time vastly out numbered) and you need to slash through hordes of fiddlers to achieve stage goals, usually by defeating enemy commander.
In most stages you can usually score 300-500 K.O. without even trying.
Google it, there are TONS of gameplay video if you are still not sure what the gameplay would feel like.
