Amazing follow on.
Campaign - This campaign was i think just right for me, it's perfect. The length isn't too long or to short. The way they managed to fit everything in like the tutorial through training Carmine. Plus the new things added that fitted in quite well. Although there were some charsacters that were a little confusing in the reason they brought them in like Dizzy and Tai. You did very little with them but yet somehow they were important when it came to multiplayer. The acts made sense and i enjoyed it a lot. The difficulties weren't too challenging until you got to Insane difficulty. Thats why thy called it insane i guess. The extras i think were good although could have been improved on like the best features must be the horde section where you battle waves of locus. The collectables part was good but i think it could have been improved easily.
Multiplayer - The multiplayer is also good but i think some things could have been improved. For example the leveling system and the fact theres no unlocking system. Although in some video's they explained how they think its pointless to spend money on something that you can use straight away. So fair enough to that it just isn't as adictive as things like Call of Duty's multiplayer. Very enjoyable however and a good game through-out.
