Infected: The Twin Vaccine is rated 4.1 out of 5 by 106.
Rated 5 out of 5 by from Maybe the best I like I really love this game and played it several times. But it is somehow difficult to describe: what is it ? First it is the atmosphere. It's like leaving your house, or leaving a train, with not much of expectations, suddenly standing on a lonely bus-stop. Of course it's raining... The ambience is realistic which I like most. The music - which normally is of no importance to me - is addictive. I had to use the hint. But not so often. There isn't anything really scary about this game I would say. But it's not the kind of game to play with your children.

Rated 5 out of 5 by from I Loved This Game! This Game Was Amazing, It Was Everything I Love When It Comes To Games BUT The Level Of Challenge Was Weak, Some Parts Were A Little Difficult But For The Most Part It Was All Very Easy, I Like My Games A Little More Challenging But Other Than That It Was One Of My All Time Favorites!

Rated 5 out of 5 by from Impressive Modern Sci-Fi BASED ON COMPLETED GAME It’s got it all. From excellent graphics and sound, to innovative HO puzzles, to challenging adventure gameplay and a gripping story. In a nutshell: • Brilliantly realistic and exciting opening scenes • Real actors incorporated seamlessly • Choose your level of difficulty, including a custom level • Subtle but ominous music accompanying threatening ambient sounds • HOs where each item you find must be used within the scene to get another on the list – the first game to do what is now the most popular adaptation on HOPs • Believable story with emotionally valid conclusion The one thing it DOESN’T have is a useful map. But hint is directional and the game logic is pretty obvious for the most part. And the one thing I wish it didn’t have was a (relatively) long black screen during transitions. But that’s just being picky. The game is simply outstanding.

Rated 5 out of 5 by from Now THIS is a HOG worth the money! I played through the CE trial of this game and I have to say I was hooked! This game provides a fantastic challenge to even the most savvy HOG gamers. Take a little of Silent Hill (you know, just for the 'creepy' factor) and add in a touch of the 'carnival of nihgtmares' and you'll have a good feel for this one. Has a good feel like Escape from Ravenhearst, Dire Grove and other like games with the little touch of unease that stays with you even after you've shut the game down. Really a fantastic trip!

Rated 5 out of 5 by from NEARLY PERFECT!! BEST GAME I'VE PLAYED TO DATE BASED ON COMPLETED GAME IN ADVANCED MODE Wow! No other word describes my reaction to this game. From the beginning, I was mesmerized with the story. It's the first game I've played that looked, sounded and felt REAL. It is a scenario that COULD happen and the characters, including mine, reacted in a realistic, human fashion. The IHOS were very clever, with gorgeous graphics and items that related to the plot. The mini games ranged from easy to medium and also related to the plot so that at no time did I feel I had stepped OUT of the plot. Too often in other games, the story comes to a screeching halt when a mini puzzle or HOS comes up because it has no correlation to the story. Not this game!! It is seamless!!! In addition,the music and ambient sounds gave realism to an already realistic game. At no time did I feel lost or confused and I found the answers to movements were logical and linear.. There is minimal running back and forth as the game literally blocks you from non-essential areas. FANTASTIC!! This is the first game that I've played that literally made me question whether I was watching a real newsreel or not. It's that well done. Don't take my word for it, play it yourself. I don't think you'll be disappointed.

Rated 5 out of 5 by from Great Game! I really do not care for HO's but since there are very few new adventure large file games available I play them. This game is not the typical HO after Ho after Ho. There is so much to do! I think this is the very first game I've played where every single object found is played. There is actually a reason to find it, even in the HO scenes. Good story the mini games are somewhat easy, liked the music and the voice overs in the cut scenes. I know alot of people skip the cut scenes but I think they just enhance the story. The only thing I didn't like was there is delay between scenes, not a smoothe transaction, like if you went through a door it took a few seconds for the room to appear. All in all I really really liked this game and wish there were more like it for people that want more adventure than HOS's.

Rated 5 out of 5 by from Inject me with MORE!! Totally brilliant game with great storyline, and superb sound tracks to keep you absorbed throughout. Lets hope the sequel is not too far away-can't wait to get immersed in another in the series. Very unique HOS, a few puzzles, voice overs, and spellbinding music make it a big 5 stars

Rated 5 out of 5 by from Surprisingly Fun! I got this game because I just seemed to come across it over and over and decided to finally give it a shot and I'm so glad I did. I really don't know how anyone wouldn't at least like this game. I loved it. I played it all day, never closed it, just took bathroom breaks & did my daily housework. The HO scenes in this game were my favorite style and I'v never seen them done quite as well as they are in this game. They were interactive but with a real purpose. Along the lines of the object i need is in a safe but the key is locked in a cage, so when I find the bolt cutters I can get in the cage to get the key and open the safe. But it was usually a MUCH longer chain of actions in the game. Of course some of the interactions were silly. Like planting a seed and watering it so the key you need will grow out of the flower bud. That gave me a good laugh. But that kind of silliness is ok because most of the time it made sense. Also another entertaining aspect is the bum you meet a few times. He's a riot. Seriously, if you get this game, the part under the overpass, look at that guy before you start talking to him, just take in his stance and facial expression. Its hysterical. The length was fine, not the longest game I'v ever played, but not short either. I can't give an accurate time because I paused a few times. But I don't feel cheated by the length, so for me that's what matters. I recommend giving this game a chance. I bet you'll like it.

Rated 5 out of 5 by from What a great game to play This is just a fun game to play. Not hard at all. You have options at start-up on easy to hard for all parts of the game. Never seen that before but all games should be like that. Music is great and graphics are super. You start playing and you do not want to stop. The HOS are different also. You have to look for items to complete all parts, different but fun and challenging. This is a game to get.

Rated 5 out of 5 by from ANOTHER WINNER!!! PERHAPS A SEQUEL??? Just finished playing this game and wanted to do this review while it was still fresh in my mind. This game was superb! The use of live actors and VOs were top notch. There was a map but it didn't transport me anywhere. The hint button refilled quickly and was also my guide from scene to scene. The IHOs were different than other games I've played. There are two lists - one for obtaining the items and another for using the items you've found. You can easily switch from one to the other and items were quickly used and didn't leave you wondering "Where does this thing go?" There is jumping from scene to scene but the hint button will guide you quickly. Congrats to the DEVS for their innovations in this game. It met all my expectations and more. Hope to see a sequel soon. Give it a try and happy gaming. :|)
