Serious Sam Voice Pack DLC

The new Serious Sam Voice Pack DLC replaces the godlike voice of Elohim with completely NEW, rewritten and humorous Serious Sam script.

Serious Sam voice has been recorded by longtime Serious Sam voice actor John J. Dick.

It also includes a new Serious Sam player model for use in The Talos Principle.

About This Game

The Talos Principle is a philosophical first-person puzzle game from Croteam, the creators of the legendary Serious Sam games, written by Tom Jubert (FTL, The Swapper) and Jonas Kyratzes (The Sea Will Claim Everything).

As if awakening from a deep sleep, you find yourself in a strange, contradictory world of ancient ruins and advanced technology. Tasked by your creator with solving a series of increasingly complex puzzles, you must decide whether to have faith or to ask the difficult questions: Who are you? What is your purpose? And what are you going to do about it?

  • Overcome more than 120 immersive puzzles in a stunning world.
  • Divert drones, manipulate laser beams and even replicate time to prove your worth - or to find a way out.
  • Explore a story about humanity, technology and civilization. Uncover clues, devise theories, and make up your own mind.
  • Choose your own path through the game's non-linear world, solving puzzles your way.
  • But remember: choices have consequences and somebody's always watching you.

Sigils of Elohim

Sigils of Elohim is a free mini-game prelude to Croteam’s first-person puzzler The Talos Principle that challenges players to solve dozens of challenging sigil puzzles under the watchful eye of Elohim.

Acquire items and relics in Sigils of Elohim on PC, Mac, Linux, iOS and Android mobile that transfer over to The Talos Principle on PlayStation 4, PC, Mac, Linux and Android K1.

Comparing The Talos Principle to a game like Portal is unfair, but immediate. The first time I manipulated a gadget to set off a part of a puzzle, I muttered how much it reminded me of the amazing and witty Portal 1 and 2, and that trying to replicate it was unwise. However, I removed my premature opinions and discovered a whole new world of puzzle and story, placed perfectly in what is called The Talos Principle.

The game starts out in ruins, immediately piquing interest and curiosity. This first person interaction makes it impossible to know who you are, or what you are doing in the deserted grounds of what seems like Rome. The land is littered with broken pillars and faulty statues, most of which are missing their heads.

Very shortly after running around, an all powerful voice beams from the skies, introducing himself and welcoming you to his garden. The puzzles ahead are a test to see if you are worthy (of what is unclear) and to strengthen your faith in him, "ELOHIM."

Without going into spoilers, I must say that the story is my favorite part of this game. Despite everything right about The Talos Principle, I’m a sucker for a great story, and very few games have the tone that this one carries beautifully and makes one question the nature of humanity. Almost every word spoken or typed holds a deeper meaning. Nothing is there without reason, and everything is set up in such a way that I didn’t feel left out of anything. There will be no regrets to finishing this game and seeing everything tie together.

Gameplay is very simple, which is nice, because the puzzles are not. Having the option, I opted for controller, assuming I could sit back, relax, and enjoy a nice, scenic mind game. I was wrong. Despite the scenery being beautiful and the music peaceful, my anxiety levels were high, attempting to freeze the laser gun that will shoot you down and sneak past the bots that will blow you up. And that’s within the first puzzles. You can’t do much on your own, only using what is provided to pass each task. It makes learning controls easy, which is nice when you have to take most of your focus into the puzzle.

There are only a handful of gadgets as well, each with a specific task that they do. Don’t be fooled though, because sometimes they are good for more than what they are intended. The puzzles themselves are short, only getting a little longer with time. Difficulty levels vary, but progress nicely with you, rather than slamming you with something impossible. There are also several puzzles per section, which gives you some options in case you get stuck. This attribute is great as the story is a heavy part that everyone should be able to complete.

What the game lacks in wit and comic relief, it replaces with promise and charm as that nagging curiosity presses you forward. There is a lot of content, which can be overwhelming if you want to follow the story, but luckily the audio tracks and journal entries are logged and easy to access at any time.

Another nice feature is the hunt for stars, which can be within the puzzle or just randomly hidden on the selected map. It had a lingering feel of Mario 64 about it. It also gives you a break from some frustrating enigmas and allows you to enjoy the landscapes. The signs are helpful to look at as well, so use them. They even mark off what you have completed, though who does it for you is unknown. Kind of spooky, right?

The Talos Principle doesn’t let down on graphics, either. Each stage and each little world is beautifully done, with sounds and music to match. Voice acting was very well done, allowing you to stay immersed in the game. The settings are almost too good to be real, which makes the game ever more creepy. Keep a look out when just walking around. There are some questionable sights on the rocks, in the water. You are clearly the only one around which raises the question, “where is everyone else?” Though questions like this will be answered, the theories I came up with thanks to the surrounding areas wwere a little unsettling.

With all of the story, the background, creepy settings, and subtle hints, I’d say this game is very replayable, especially if you are like me and forget how to do the puzzles. I know I’m one to miss things the first time around, so going back is always good.

Despite the eerie feeling I got every time I turned the game on, I was so compelled to read the QR codes on the walls, left by others before me. I wanted to understand the notes in the computer library and I wanted to know who ELOHIM really was, and what he wanted with me. All of this and more is explained if you are strong enough to pass over 120 puzzles in The Talos Principle.

A computer terminal in the game asked me why I wanted so much to prove I'm human. I spent like 10 minutes thinking, unable to answer.
Thought this was just puzzles, ended up on one of the most philosophical rides a game has ever taken me. 10/10

"The Talos Principle" is one of the most enjoyable and rewarding gaming experiences I've EVER had and I've been playing video games since the Atari 2600 days. There is a reason why "The Talos Principle" is a hit among critics and the player reviews are "Overwhelmingly Positve." For me this is a new classic. A game that catches lightning in a bottle. One of those games that scratches an itch I didn't even know I had.

NOTE: If you think you might get this game, I'd recommend against watching video and looking at player screenshots. They are both highly likely to contain spoilers and inadvertent puzzle hints, both minor and major. I only played the demo going into the full game and I feel the experience was better for it.

This is a first person, sci-fi themed puzzler in which the player, an artificial intelligence, is left to complete puzzles by using a series of tools that are introduced throughout the game. The first tool is the Jammer, a tool that jams electronic devices and force fields. Another tool connects to and aims laser beams. You'll also learn that tools can be used in combination, keeping the progression interesting. Solving a puzzle rewards the player with a sigil (tetromino) which are then used as puzzle pieces to unlock new areas when arranged correctly in puzzle mini-games.

The only conversational contact the player has is with another AI program that often presents itself at computer terminals as the game progresses. The player is also, through communicating at the terminals and reading information displayed on them, left to ponder the role of the disembodied voice known as "Elohim", as well as the meaning of life, consciousness, being human, being alive, free will, and the afterlife.

The game itself is solid. Easy and tight controls. Very nice music, sound effects, and voicework. Clean, often beautiful graphics. Intelligent writing. No profanity or violence. Menus with many options like FOV, character speeds, FPS display, time display (something I never used as I chose to take my time), etc. Basically, I found the setting menus to be thorough.

Many have compared this to the Portal games, which is high praise. While both offer clever puzzles and a high quality experience, "The Talos Principle" only rarely depends on any sort of physical dexterity or reflexes. With those few puzzles that do require quickly timed movement, even the most casual of players shouldn't have any issues whatsoever.

While the presentation and story are high quality, it's really about the puzzles. What makes them so satisfying? First, puzzles do not need to be finished in an exact order. Leave one alone for a while that you are having trouble with and try again later. I found it interesting how I'd find myself struggling with a puzzle but after a day or two, the solution would become clear. It was almost "scary" when realizing how hard at work my subconscious was. I would also think about certain puzzles when not playing and come up with new things to try out. I found myself overthinking many times when the solution was much simpler. Also, just when I thought I had a handle on a "recipe" that certain types of puzzles used, the game would throw me a curveball, forcing me to deviate from previous "patterns".

Some puzzles, even of the harder variety, can be figured out quickly depending on the player's frame of mind, while "easier" puzzles (those without numerous elements) can be trickier. You know the puzzles are good when you find yourself wanting to do "just one more" before ending a session. And puzzles can often be completed in more than one way. I found out later that some solutions I used were much much more complicated than they needed to be. This dynamic of overthinking vs. underthinking is what helped make my time with "The Talos Principle" so interesting, as well as thinking out a solution before acting vs. using a lot of trial and error at other times.

This game also encourages and rewards exploration. There are stars to collect, which unlock additional content in the form of more puzzles and ultimately an additional ending choice (there's a main ending and two possible side endings). These stars are often "puzzles within puzzles" and gathering them is rewarding and can be quite challenging. It's not just a matter of "hide and seek". For example, a star may be within a puzzle and behind a door (force field). It is up to the player to figure out how to reconfigure his/her solution so that an additional door can be opened. There is also an ample amount of "Easter eggs" to find, many of which are interactive and well worth seeking out. Many are references to other games, like Portal 2 or Papers Please. Pink Floyd is honored with one as well.

Keep your eyes wide as you traverse the puzzles and worlds. Even just finding ways to exploit the simulation is fun, for example, finding a way to climb over the outer walls of a puzzle and into "out of bounds" areas (where there are some Easter eggs to find). Or "breaking" a puzzle by finding an "unintended route" to the finish by climbing over a wall, or walking above one. (This accounts for a lot of my game time).

"The Talos Principle" should appeal to a wide variety of players. I spent about 80 hours on my first playthrough and a less thorough playthrough will of course take less time. I then replaid for 100% achievements (which I usually don't do). I suspect that many of the people finishing Talos in "20 hours" are not doing everything (reading files, getting all stars/doing the puzzles they unlock, looking for easter eggs) and likely to be using a walkthrough here and there. You can play this game as you want. Complete the puzzles in order or don't. Do them fast or slow. Solve star puzzles or don't. Don't read every piece of information at the terminals if the story side of the game doesn't interest you. Look closely for Easter eggs or don't worry about them at all. Try out the side endings or don't.

The support is very good with developers active on the Steam forums should anyone have issues and updates have been released to fix and add things (like an added special settings menu for "motion sickness", a speed time function, additional language support, etc.).

NOTE: The demo is also good, yet only a taste of the full game. It ofters a solid introduction to gameplay and some clever puzzles. There is even another free game called the "Sigils of Elohim" that is made of tetromino puzzles. Solving them will reward you with codes that are then entered into the menu of "The Talos Principle" for bonuses. These do not change the core game at all but, for instance, you can get stars with these codes.

All the regular stars will still be in the game to find. If you get the codes for bonus stars (three in total), you will start with three stars in the full game. So, you'll be free to leave three stars unfound if you wish and still receive the bonus content for finding all of them. In other words, if you start with the bonus stars and then go on to find every star in the game, you will finish with an extra three stars.

PS: If you get and finish the game, check out my screenshots if you want (NOT before you play). Some hint at additional "challenges". Like getting a picture of the blue man visiting the greedy man and living to tell about it.

Game "recipe" so far:
--> "Portal 2 memories are back"
--> a lot of great riddles - starting from easy to hardcore
--> different kind of riddle types like the linear ones, special ones to get stars and secret bonus ones
--> smart and sometimes really difficult but exciting riddles
--> deep and philosophic interactions with the PC terminals
--> a light but acceptable off-taste: A kinda "quite" atmosphere unlike Portal 2
--> different and wonderful spots to solve the riddles

Does this sound like a very tasty adventure and riddle game, or not?

A fully review with lots of more info after finishing the game! :)

Possibly the most existential game I've played. Though it is, at it's core, a puzzler. The puzzles are often complex, a few head-scratchers, but sometimes require a more reductionist approach. What may seem complex at first may turn out to be very straightforward. At times it requires you to question the assumptions it has itself given you. Good exercise for the whole brain, as it doesn't train through repetition but demands both creativity and reason, both abstract thought and technical logic. Along with the puzzles a story gradually unfolds. Concepts of self, place and time begin to dawn while another mystery deepens. I like that the story is only hinted at and alluded to, so that you formulate the idea on your own. It makes it that much more meaningful and powerful. It is likely the most existential and eternally relevant topic one could imagine, and the story itself would make a fascinating novel or film. My only complaint is personal, that the game seems to make assumptions concerning beliefs, more specifically, that having them is a universal quality of humans. But this is not at all the case. At times it seemed as though the authors had an agenda to express their own beliefs, but perhaps this was just my suspicion of beliefs in general. The dialogue trees where multiple choice and never once did I actually agree with any of the choices. So it felt like being pigeon-holed and I ended up arguing for a point I didn't actually think was correct. Other than that minor brow-furrowing frustration, I really enjoyed spending time in the beautifully rendered game world. The music was lovely and atmospheric. Extremely smooth play with a good variety of menu options. It's rare that a puzzle game addresses both hemispheres of the brain as well as the subconscious mind. I strongly consider it a work of genius. Oh, and if you decide to play it, I left some messages for you. ;)
