For those unfamiliar with the Portal of Doom, it is a computer game developed by Valve Corporation. The object of the game is for the player to defeat the portal, a mythical construct made by the elder god Orcs to transport his soul into the world of the dead. The portal was used to lure the hero into the world of magic and danger, and there he must defeat the evil dark lord Skogul to escape from his own destruction. There are many similarities between the two games; however, there are also many differences as well.
The main difference between the two portals is that the first one does not function like any normal game where you have to find the items needed to progress. It is a very interactive game, and you actually have the control over the actions and even the timing of when you enter the portal. The game takes place on a single interface, called the portal, and you can use your mouse to maneuver the camera and select items you want to pick up. The game is quite challenging, but this is part of the fun.
The other difference is that the portals in Portal of Doom do not disappear after you leave them. The portals will remain in the middle of the screen unless you move the mouse to the left or right. When you are done using a portal, you simply click another to put it back where it was. There is no save feature in the game, nor are there any objectives you need to complete before you start the game. This makes it an easy game to play and is considered to be one of the most balanced games on the internet.
The music in Portal of Doom is very eerie and haunting, especially when the screen shakes when there are portals close to your location. However, it is possible to disable the music and sound effects, so that you do not have to worry about too much if you are scared. However, you can turn these off if you do not feel like dealing with the creepy atmosphere of the game. The graphics are fairly primitive, but as long as you do not have a good system configuration, you should have no problem playing the game.
One interesting thing about Portal of Doom is that it was the first game that lets you use portals. You need to find and use the cubes to link with the other portals that are around you, but each portal has a different color and is represented by a different icon on your keyboard. To use the portals, you have to click on the appropriate icon and be brought to the new location. Also, the game requires you to use the mouse to point at an icon to bring up its details, which is great for someone who has trouble using the keyboard.
In general, Portal of Doom is a game that is challenging. The goal of the game is to keep all the portals you have built with your cubes linked together, by destroying all the enemies that try to get through. You will also need to get through the many challenges and puzzles set up by the various creatures that are present in the game. Even though this game is difficult, it does not make the player feel as if he is being beaten down by something. Rather, you will feel invigorated as you see your portals get destroyed by the monsters and continue to rise in power.
