Simply put I loved the original Dead Space and thus when Dead Space 2 came out it was a day 1 purchase for me. After finishing the game (~14h) and playing multiplayer for couple of hours this is what I thought.
***********PROS************
A SURVIVAL HORROR: While Dead Space 2 is slightly deviating from Dead Space 1 in terms of it is being more cinematic (more dramatic cut scenes, more depiction Isaac as a character etc.), Dead Space 2 is still a survival horror. You will have to be careful of your surroundings, you will have to be careful about conserving your ammo and you will have to have to use different items you gain in the game very wisely to get through the game on normal or harder modes. So unlike games like Resident Evil, which has moved to purely action/adventure, Dead Space 2 is still a survival horror.
ATTENTION TO DETAIL CREATING SPACE ENVIRONMENT: One of the reasons I loved Dead Space 1 and now Dead Space 2, is it is horror in space. In Dead Space 1 you are surviving in a space ship abandoned in Space and in this game you are doing similar in a city in space that is going through similar terror. While you may find these two settings very similar, there are some aspects that truly distinguish Dead Space 2 from 1. One of them being taking place in a city, you will have much greater variety in environment compared to Dead Space 1 and everything is designed so craftily that it actually feels like you are in the futuristic city in space. I truly want to give you examples, but it is hard to do it in words and without spoiling the gameplay experience for you, so just take my words for it.
UNEXPECTED SURPRISES: This is probably the best aspect of the game and makes it actually a horror. There are so many parts in the game (and I mean so many) where you won’t see things coming and I am not just talking about enemies popping out of closet, but some really good stuff. I truly wish I could tell you, but I truly don’t want to ruin the game for you.
BETTER IN SPACE GAMEPLAY: Like last game, you will have zero gravity and Oxygen less space areas, but in this game there will be a variety of things you will be doing in Iron-man like space suit. I simply loved it, especially the parts that are highly cinematic.
VARIETY IN ENEMIES: Just like Dead Space 1, there is plenty of variety in enemies. While a lot of enemies will be similar to Dead Space 1, there are some very unique new enemies. Having variety of enemies truly prevents the game from being redundant and keep things exciting.
VARIETY IN DEATHS: This is a strange pro to list, but play the game and even if you are a good player try dying with the hands of different enemies and different environmental hazards. The number of brutal ways you can die in this game will surprise you. I personally loved it.
VARIETY IN WEAPONS: Again most of the weapons you get are from Dead Space 1 (which are great), but then you will get also some new different type of weapons. The best part of these weapons is they have alternate fire. So this makes using them very strategic. The best thing that has been about Dead Space series is it is not simply about going around and shooting enemies. Rather, it has been about strategically fighting off the enemies. There are parts in this game you will get hordes and hordes of enemies coming at you. If you simply try to get them by just using one weapon, they will punish you. On the other hand, if you strategically use your weapons’ fire and alternate fire, you will be able to survive through the terror and move forward.
PLENTY OF UPGRADABLES: Just like previous Dead Space you can upgrade your suit, your rig, your weapons etc. In this game though you can get different types of suits. I personally have loved this addition. This truly adds an RPG element and promotes you to conserve even more so you can by nodes to upgrade as many weapons as possible.
AWESOME BEGINNING: Usually in my reviews I only consider gameplay etc. as pros and cons., but the beginning gameplay for this game is so unique that I have to put it down as pro. Unfortunately I can’t tell you more without spoiling so play and find it out.
TWISTS IN THE STORY: There are few twists that you may be able to predict, but others I guarantee you won’t see coming, especially in the end. Every crazy thing you may read or see has some sort of meaning. Unfortunately another thing I can’t describe more without spoiling.
NO ASTROIDS: Yes this is another thing I wouldn’t usually list as pro., but asteroids in Dead Space 1 annoyed me so much that I am so happy they don’t have them in Dead Space 2 or anything of similar nature.
BONUS GAME: As of now (02/2011) If you buy this game for PS3 form Amazon, you will get Dead Space Extraction for PS3 move for free. I can’t say for the future though.
MULTIPLAYER: While I am not into multiplayers these days, I still loved the the multiplayer for this game, especially the part where you can play nacromorph. This truly adds great replay value to the game.
MANY DIFFICULTY MODES: There are 3 difficulty modes above normal. So if you are a completionist, this game will take you a while and provide you hours and hours of entertainment.
************CONS.*****************
LACK OF GOOD BOSSES: Don’t get me wrong there are some good bosses in this game who will kill you in some of the most brutal ways possible; however, I had better expectations for them. Especially for the last boss. Kind of disappointed.
INVENTORY: Dead Space 1 and 2 are the games where you truly have to conserve the ammos and items and for that your inventory space is very important. Just like Dead Space 1, in this game there are levels where you will go long sequences without seeing a store where you can rearrange items in your inventory. During these long sequences you will acquire quite a few god/silver/bronze semiconductors (huge chunks of credits) and schematics for new items and they will occupy huge part of your inventory which should be used for ammos and health. I personally found it annoying. They should have separate space or should not take any space in your inventory at all.
************CONCLUSION*************
Pros for this game clearly outweigh the Cons. If you are a Dead Space fan or like horror games, this game is a must. So do yourself justice and buy and play it at your earliest opportunity. I give it 9.5/10.
