"It's true the game does the Painkiller thing, making multitudes of monsters to mob you mercilessly, but as with the environments they forgot the whole variety thing, and you only ever seem to fight two kinds of aggressive Roomba and a few palette-swapped wheelie bins. There's really no way of saying this without giving ammunition to conservative anti-game campaigners, but there isn't as much fun to be had in shooting robots as there is in shooting organic lifeforms. When I fire a rocket into a cluster of charging monsters, I like to know that the cleanup will have to be done with a mop rather than a broom! It's hard to explain, but surely we can all agree that the lawnmower scene from Braindead just wouldn't have been as memorable if it had been taking place in the audio/visual department of Harvey Norman's."
