Monster Madness is a comic hack n slash. If you've ever played Zombies Ate My Neighbours by Konami, you'll feel right at home - the only difference is that instead of saving neighbours, you'll just be fighting off hordes of scary creatures b-movie style.
The games very light hearted and ideal for a quick pick up and play but don't expect it keep you entertaine for hours. The 4 player co-op mode works very well though so you can have extra laughs with that.
I picked this up in a sale and enjoyed it for what it was - a simple but very playable game which you can dip in and out of.
