While I found RE5 entertaining and a decent enough game, it just felt very different to the early RE games. While I accept that series' need to evolve and develop with the times, RE5 only partially succeeds.
The fast-moving 'zombies' make a return from RE4, which at times makes the combat sequences nerve-wracking as numerous 'zombies' close in on you quickly. The addition of a two-layer mode is also quite welcome, although the AI at times, is horrible.
Another welcome return is of the laser-sight, to indicate where you are aiming.
However the game feels far too linear. It's very much a case of moving from A to B, and then onto C and so on, with a very straight-forward direction to go in. It doesn;t take a genius to work out what to do and where to go, whereas earlier RE games had a faint RPG-puzzle-solving element to it.
The storyline is decent enough. I'm not 100% convinced by the African setting though. For some parts it works very well, negotiating your way through dingy shanty towns, but some more dimly-lit night-time scenes would have been nice to potentially add more horror and creepiness to the game. The abandoned mine section (with either yourself, or yur partner carrying the lantern) was deliciously creepy.
Another flaw, is that it no longer feels like a 'survival horror' anymore. The horror element has disappeared, which is a real pity. Again, earlier RE games had a real 'fear factor' to them. 'Dead Space', manages to do this (although 'Dead Space' is equally linear as well). In all fairness, these are not things that have come about overnight in RE5, it's been a gradual change over the last few games.
I don't want to sound like I'm criticising the game too much, it's still a decent game, definately worthy of purchase, but fans of the old-school RE games will come away slightly disappointed that some of the old classic characteristics of RE games have been displaced. It's better described as a 'survival action' game, than a 'survival horror'.
