I am a gamer of over 30 years standing. I can recall playing games on my cousin's orange Grandstand console, circa 1978, and playing Space Invaders in greasy Greek-owned cafes during the early 1980s (Aah! Sweet memories). So, I think I know by now, what constitutes a good or bad game. This is definitely the former! When playing, it became obvious to me that it's been heavily influenced by games such as Metal Gear Solid, which is not a bad thing. But what the developers have done, is minimize the length of the FMVs. So you won't have to sit through long pretentious sections, without using your joypad. Another influence, is the 1983 film Krull, which featured a Glave weapon comprised of 5 spring-loaded blades. But in the game this weapon can do much more than it did in the movie. For instance, you can throw it at frozen or electrified objects in order to energize it, then freeze or electrocute your enemies!! This is fantastic fun, whenever you pull it off. And as for the complaints about not being able to save wherever you are, that is not the case. If you quit, then select "Continue" when restarting the game, it will take you back to wherever you left the game previously. And anyone that admits to looking up cheats on the internet, is NOT a true gamer. The AI of the baddies is pretty good, but not undefeatable. So you won't get too frustrated with the game, even if you are a newbie. It has obviously been designed with playability in mind, so that anyone can grasp it and enjoy it. Having said that, even an oldie like me, is still stuck on the final level boss. Have no fear. I'll let you know when I beat him.
There are also some excellently designed levels, especially the graveyard level which leads you into the church where you will meet...Oh, I better not spoil it.
I forgot to mention the Predator-style invisibility suit you can win. Ooops!
