Well I am suprised. The vast majority of reviews and critiques on Legendary have been less than complementary, with a lot of mud slinging going on. And agreed, here and there are instances where it feels technically slack, or stupidly out of date - but generally, taken as a whole this is a wonderful game, with some hugely atmospheric moments, and some real highlights if you take the time to play through.
Bad and good things then: Linear as hell, you're channelled along one path with no deviation in any way. Often the barriers in your way are approximately ankle high, but for some reason Deckard can't jump more than about 6 inches off the deck and thus has to detour around small walls, kerbs, tiny piles of masonry etc. Its ridiculous dated stuff, but not a game breaking thing.
The AI is thick. Certainly enemies run around taking cover, but they'll happily take cover then leave their heads poking out taking pot shots at you (and mostly missing) allowing you to take you time lining up your shot and popping them in the noggin. Emergent AI this is not - again it feels fairly dated, but its still entertaining stuff.
Graphically, well it ranges from gorgeous (honestly! it really does) to the chronic, but overall theres a level of shine and polish thats pleasing on the eye. You'll spend a fair bit of time roaming dingy sewers and ruined buildings, which are all nicely done, hugely atmospheric with decent water and lighting effects, nice texturing and good smoke etc. Occasionally you'll hit the odd bland area, but mostly the graphics are impressive.
The monsters, well, again they're a mixed bag, and often its the implementation and design that frustrates more than the beasties themselves. One of two werewolves are a little creepy, a little exciting. 30 werewolves all spamming the screen at once becomes irritating, same with the ephemeral flying children things. They do gradually become annoying when attacking in numbers.
Technically we're a little out of date too, with some mad clipping errors, limbs through walls etc, curious physics here and there. Messy and slightly amateurish, but only really a problem if a werewolve dies with his head stuck in a wall, meaning you can't chop it off, meaning it regenerates and needs killing again.
Read as a checklist of features, I have to say Legendary sounds awful - but its really not, the whole thing gels very well and becomes a cohesive and excitingly atmospheric trek through the ruins of the world with some big exciting stuff going on - you're taken from the shattering destruction of New York and London, with explosions and screaming and Griffins everywhere, to the dark quiet journeys through the sewers, populated by the bodies of those who tried to hide and the odd werewolf here and there.
Give it a go. For a tenner its hard not to recommend, and like me you might be hugely and pleasantly suprised.
