For those put-off by the demo, the full version is much like the first two games in many ways - which is a good thing.
It is definitely challenging at times, as you are just over-whelmed by strategically placed enemies that are fired down from above all around you at times, making your head spin as you whip around trying to rid yourself of the ranged attackers without forgetting about the approaching melee monsters.
Not sure what they are thinking with the weapons - I am so sick of using the slow shotgun at this point - that some more variety and ammo sure would make things more entertaining.
That said the shotgun is fun, it's just used too much throughout the game, and enemies just explode into a green gassy goo, apparently to avoid over-burdening video cards.
Not even halfway through it, as I'm stuck on a particularly challenging area on normal difficulty - and getting past it will make me feel as though I accomplished something at least.
SSII has a very old school arcade feel to it - which is great for me - it's all about reflexes and wit - and the size of the enemies at times is awesome as they crumble and explode around you.
The story is much better too in this game, for what it's worth, as the Simbas assist you somewhat through the early stages.
I wish I had more time to play the game lately as I am thoroughly enjoying it so far and want to get into the different levels.
So far, big thumbs up Croteam - you still seriously rock.
