Dishonored: Death of the Outsider

You can chat with rats.
Edit: After talking to every rats encountered on map, the rats sound annoyingly horny.

The playing time is relatively short, the areas are structured more like a sandbox and you have around 5 levels with tasks, as well as the option of how to complete the mission (example: bring a target person to person A or B, your choice), which brings a bit of variety.
Due to the lack of a long-winded story, it suddenly plays like a quick Hitman level, i.e. spawn, kill the target person and disappear again, either stealth or full action. You can like it.

I've played all the Dishonored games, and I will say that while it doesn't mesh as well with D1 and D1, Death of the Outsider is still a great sequel. That is to say- DoTO is the 'worst' of the three games, but that's not to knock it- it's still really good and holds up really well to its predecessors. If you liked the other games, chances are you'll like this one too. Despite my criticisms, I still found the game really good (I played it through twice within having it for less than a month). The story is compelling, and it's good to be back in the world and see the characters again. The visuals and storytelling, especially in the final moments are really cool, and it's great to finally 'explore the unknown' that we've been tempted by from the first two games.
However, it feels more like a DLC than a full game. There's less missions, less characters, just less going on overall. And, it's far more grim. My first playthrough was a Clean Hands playthrough, I made sure to check my stats and I didn't kill anyone- but it didn't change the environment at all, and didn't change the ending. There is no punishment for doing the game the easy way (high chaos) or the hard way (low chaos). And, there isn't any smidgen of happiness- I'll be so straight up. Where the other games had light-hearted, warm moments (even between NPCs, like the lesbians running away together in D2, or Emily and Corvo's relationship in D1), DoTO's moments that were maybe meant to be seen as sweet always had sad undertones- leaving them bittersweet (mostly sad, in my opinion). Obviously not every moment should be sweet, but from a writer's perspective there needs to be a balance that just wasn't there. It made it a very depressing playthrough, and I had half a mind to only play it the one time because I just found that there was no glimmer of hope to 'keep me going', if you will (I played D1 twice, D2 three times, so I really enjoyed replaying the games obviously). That's not to say that the sad moments didn't serve a purpose- but don't go into this game expecting the chaos system to matter, and fully expect to find no 'glimmers of hope' throughout the game (I personally found that the game was mostly sad). Every single small NPC interaction, every big game moment- it's like a punch to the gut. The game gives you glimmers of hope only to crush your expectations and give you the worst outcomes regardless of anything you do. It's a depressing story, in my opinion. Far more depressing than the other games ever got (or the other games did a better time balancing out the narrative).
Now, this may be just my computer, but Dishonored ran smoothly on my computer. Dishonored 2 required maybe five minutes to load up once I was in the level so it wasn't laggy. DoTO took closer to twenty minutes or more to get less laggy- and it would still run slowly even on low resolutions and other frame-saving settings. This might only be an issue I had with it, so take this with a grain of salt, but it's worth noting in case others might experience similar.
The game is shorter than the others, with a lot less replayability. While I found that there were a lot of options on how to get into areas, the game did feel like you had less choice than in the other games. It also reuses a lot of assets (which isn't a bad thing, I couldn't care less about that), and maps. I got this game as a gift, but I wouldn't pay $30 for it. Wait until it's on sale. The game isn't bad by ANY means, but I wouldn't say it's worth $30 when it feels more like a DLC to D2.
Billie's powers are neat, and I get why the devs wanted hers to differ from Daud, Corvo, and Emily's powers- but they're either really good, or really bad (Semblance is really neat, but I found Foresight and Displace to be far more tedious than they were worth). Luckily, the game does have a mode (Original Game +) where you can swap Billie's powers for Daud's Blink, Darkvision, and Emily's Domino. I found that to be better, since I wasn't having to click twice for Displace, and I could aim with Blink, where you can't aim as easily with Displace. However, it seems like you have to complete the game with Billie's powers before you can unlock Original Game +. While I get this is to get players to play with Billie's powers, they just aren't as player-friendly (in my opinion). Still, struggling with using her powers wasn't game-breakingly bad by any means. I could just struggle with it and no one else does- I'm not great at videogames.
The contract system is VERY neat. It's essentially side jobs you can complete during a level. That can look like robbery, murder, or helping others out. It's such a great system and I hope to see it again because it added another layer of depth to the levels that made you want to play longer.
Despite the bittersweet nature of the game, where it felt like you were constantly getting sadder and sadder as you progressed, I still really enjoyed it. I'm eager to see where (and if) the franchise goes from this game. I like the theme playing around with morality, and if evil and wrongdoing are a choice made by an individual, or if you can lay blame upon higher powers. I think that makes the ending more powerful (regardless of what ending you get). The Dishonored franchise has a long-running theme of forgiveness, and breaking the cycles of evil. This is no different, and I love it. Again, while DoTO has its flaws, I don't think they take away from the compelling storyline, and overall gameplay. It's a good game, and I really enjoyed it.

It’s a great game and (for the moment) finale to the dishonored franchise. A few quibbles: Rosario Dawson definitely phoned it in with voice work. I have not heard a less compelling performance from an otherwise great actress, but I guess it goes to show you that Voice acting is an art unto its own. Second, I don’t like that dishonored 2 did away with the mystique of the outsider by explaining to us that he ascended into his power by being sacrificed by a cult, but I found the way this story incorporated the new lore to be really unique and compelling. Over all, I can recommend it

Mechanically, the best game in the Dishonored franchise.
No more Chaos system, so you can KO or kill as you please, though I'll never stop being a fan of solving problems using non-lethal methods. Using 'Semblance' to quietly slip through guard patrols wearing NPC's faces, or even take out entire patrols one at a time, never gets old. 'Foresight' is one of the best ripostes to anyone arguing against 'x-ray vision' in stealth games, as this ability relies on players scouting for themselves and it's a very limited power compared with Dark Vision in Dishonored and Dishonored 2.
The weapons and gadgets are great, and there's a good mix between lethal and non-lethal options. It's fun using hyperbaric grenades to KO a small crowd of distracted NPCs, but it's also fun to rip a few limbs off with lethal-mode hook mines.
Mission-wise, infiltrating and robbing the Bank is by far the standout event of the game, and the range of options for how to tackle it felt substantial enough that I wanted to replay it and try something new the next time around. There's even a Dark Souls Easter Egg in there. Probably I'd pick the last mission as the weakest, which is a shame. By that point you've unlocked all your powers and should feel like you're being unleashed on a playground, but it's actually a corridor.
As far as stories go, I've always found the main narratives for most Dishonored content aren't as interesting as their components, and I'm a touch resentful that the writers chose to reveal and kill off so much mystery in The Empire of the Isles. Daud's story in Dishonored's DLC remains the best tale in the franchise, in my opinion, and probably deserved its own game. All this is to say, I think DOTO has the weakest story overall.
That said, all the characters are great. The lore and world-building is fascinating to read through. I'm glad we got to say farewell to Billie Lurk, though Daud's part in this tale feels like it needed just a bit more substance.

The story may not be nearly as good as 1 or 2

The game may be exceptionally short

but it gets the one thing right that plagued the other two. Combat, the combat in this game is easily the best in the franchise, coupled with the continued impressive stealth mechanics, this game is good, but very short.

A pretty decent game with retro futuristic theme. takes place in a coastal city of Karnaca , you play as an assassin fighting to fulfill your mentors last wish .
The game it self is mostly based on stealth , to do your task without being seen or dropping any bodies , but well you can raise hell as there are plenty of alternative ways to achieve your goal in every mission .
short game though , it should have been a DLC to the second installment of Dishonored .
