The Red Faction: Armageddon Demo is the sequel to Red Faction: Guerrilla. It is set underground on Mars in the mines.
The story starts suddenly with your co-workers trying to kill you.
You start off with a charge launcher and only after half way through the demo do you get an assault rifle. The other weapons are interesting being a magnet gun and a singularity cannon.
Using L2 to rebuild structures is fun at the beginning but is a bit over used.
It is a closed-world game unlike Guerrilla and I hope that this is not the same in the full game.
All in all, I think that so far it is a major disimprovement from Guerrilla. Yes, the weapons (but no hammer) and the exoskeleton are fun but the underground is a confined area and also very dark which gets on my nerves. I don't think I will be getting this game.
