I have played through both demos, and the game plays great... no lag in any way on my system at max settings... but is there more to the full version... is there a plot... is there any role playing... is it worth it... or is it just a hack up those zombies and spray blood everywhere fps game?
Face it, the game just flat out rocks. The plot and story are paper thin, the zombies are plentiful, and the weapons are unique and hilarious.
As stated in this month's PC Gamer; Painkiller is a game where you enter a room, run backwards and strafe while shooting madly, and move on to the next room. Rinse and repeat.
Since you've played both demos, you've seen exactly what the gameplay will be like on all 24 levels. I played through the entire game with a huge [-peep-]-eating grin on my face, just because it was such great mindless fun. And yea, the graphics and physics are pretty killer too. I think it will go down in my gaming history, the time a ninja jumped off an upper level towards me and I pinned him to the ceiling with the stake gun. Priceless.
