Game Testing tasks -
1. You will actually play through the entire game and make sure that everything works properly. This means that they have to test out all the weapons, objects, cars, trucks, animals, backgrounds, etc, to make sure that everything works right and that there are no glitches. When you think about all the different components that go into video and computer games, there can be hundreds of thousands of different combinations that have to be tested by a game tester.
2. You also have to test the "limitations" of the game. This means that many of the players who eventually buy the game will try to do things that the game was not really designed to do (such as creating the largest army or getting to an extremely far away point on the map). So, the game tester has to anticipate these things and try out some of the crazy or odd things that other gamers might try to do to be sure that the game can handle the stress or not.
3. You have to make sure that the game can actually be beaten. This means that they have to try to beat the game itself in all the possible ways, since there are all different types of gamers who will try to beat the game in many different ways. Game testers have to anticipate this so there are no glitches or bugs when gamers try that particular path.
4. You will also be responsible for making sure that the game works correctly on the system that it was designed for. Such as in the case of computer games, a game tester has to make sure that the game will work with a large combination of different brands of hardware, video cards, memory, and so forth.
