I at first generally enjoyed the game - not as great as the other Dead Spaces, especially with the overzealous add on content, but the core game was good enough. The weapon crafting system provides a nice way to customize your loadout, but you are stuck with two weapons, requiring you to bolt on a second weapon to a another gun. The problem with this is that reloading one weapon stops you from using the other, and there's a huge delay between using the two guns on the same frame, which is inexcusable in a game where you have limited space to evade, the dodge roll is largely ineffective since necromorphs can "heat seek" mid attack animations and enemies are rushing you faster than Issac can move out the way of. I understand Issac is an engineer and not a soldier, but I died too many times in this game because Visceral (probably at the request of EA) made this game more like a shooter, yet didn't compensate the rest of the game mechanics other than giving you more ammo pick ups. The idea is that you're supposed to build the most efficient weapon combinations, but the weapon loadout is more cumbersome than it needs to be - you only have two weapons slots (one which is stolen by a story mission weapon) unlike previous game where you could get up to four and having a Plasma cutter with a rotator cuff takes up that entire slot (though, there is little to no need for a rotator cuff in DS3 compared to previous titles, but it's silly that a weapon from a previous game takes up such space)
I put hours into the game, nearly beating it, until I reached a moment where the game glitched out and I fell through the floor geometry and could not progress. I restarted the game since I "probably played too long". Once I restarted, I lost my progress of finishing a previous mission to realign a power array. This was a somewhat difficult point in the game and while I could do it again, I'd rather not. Dead Space 3 has an absolutely terrible save system, as you can only manually save through exiting game or reaching a certain checkpoint. However, if you don't reach the check point, even if you finished a room, puzzle, or mission objective, it doesn't matter if the save icon didn't show on your screen, causing you to loose progress if you left the game for whatever reason. While save issues are prevalent in some games, this is inexcusable for a modern linear game that doesn't give you the ability to directly save at any time. Ironically enough, the game may remember how much ammo was in your gun before you died (requiring you to reload your gun after you start over from dying) or some items that you picked up, but it doesn't remember where you actually where or maybe what modifications you made to a gun (depending on when you pass a checkpoint). It's the strangest, most "selective memory" kind of file saving that I've ever seen in my 20+ years of gaming.
Another annoyance is that some missions are co-op only, so if your not playing with a friend, or if you can't get a player because nobody else is interested in playing this anymore (What the hell where they thinking?) then you are missing out on content. I hope and assume these are item harvesting quests and doesn't contain potential story info. And like most modern linear games these days, you often reach "points of no return" for certain missions if you walk past certain spots or trigger a cutscene. Wanted to place a scavenger bot at a place you missed? Forgot an artifact or other pickup? Too bad, you'll have to play the game over again to do so. I loathe when games do this.
The combination of the combat mechanics, the save system and the game breaking glitch among other annoyances caused me to the close the game. You could go worse, but those issues felt like an utter spit in my face and disrespect to the time I invested in the game. I'm going to uniinstall it, though I will go back just to mess with the Arena mode to see what it's all about.
