Oooh, Tale loves the game.
What do you love about it? What about the SP was excellent?
I think I primarily enjoy the mix of TPS and hack and slash. Open fire on an incoming horde, then when the magazine empties, start slashing right into them. If things get bad, switch on fury. Or switch to a melta. Or dodge out of the way, try to regen armor/reload. It ends up just feeling like a sword and gun wielding badass taking on hordes of orks. Or Chaos Space Marines. There's something about dodging plasma fire to bash a guy's head in with a hammer.
Difficulty is a mixed bag. Expect deaths that you can only attribute to "too much **** is going on for me to really pay attention to." Likeseveral rocket launcher orks firing on you while you're stuck in a melee. Or other range dependent fights while you only bothered to equip for power hammer.
But at the opposite end, you've got moments in the game where you're equipped with assault packs and power hammers. Literally nothing will stop you.
For however much I love it, there's several people around here who felt it was repetitive. I can't stress trying the demo enough.
