In Quake 2 Walkthrough the player is aiming to gain 9 achievements in order to complete the game. Depending on the skills or experience of gamers it can take 3 to 7 hours to successfully complete it.Check out also Quake 2 cutscenes.
Your mission in Quake II is to destroy the Stroggs as you are fighting as a member of the Earth’s forces. All 9 of the achievements are centered around defeating the Stroggs. The game seems easier to play on the Xbox 360 version compared to the original 1997 PC version. The new version comes as a bonus disc for the Quake 4 game.
Before you start on gaining the 9 achievements just remember that the obtaining of them does not increase your game score, you are simply demonstrating that you have the skill to grab all of the achievements. Some players have not bothered to play Quake 2 because of that.
Wherever you are in the game there are secret stashes of weapons and power ups so look out for these. The achievements are in the same places no matter what difficulty you pick, the only difference is that you will have to stop more enemies to reach them.
On the first level there is a shotgun and a silencer to be found, plus grenades and health boosts. As soon as you have killed all of the guards you go back up the stairs and by reaching the lift you have gained the first achievement.
For the level 2 achievement you have to fight your way out of a large room full of guards, remembering to grab the hidden machine gun on the way out. Take a left after picking the gun up, you will need to kill more guards, by going to where they came from you will pick up a quad 4 to give your guns 4 times the power. Carry on until you find the stairs to the sewers and the next level.
Once you have gone through the sewer you have reached the Communications center. Just head for the factory area and then the Computer Room killing anyone you meet. Once you have gone all the way round you go back through the door you came through to begin the level.
In between the last two levels is a secret level where you find a secret weapon, that will be really useful to complete the game. Then you are back to level 2 only this time you will find another shotgun.
You can explore on all the levels as well to make sure you uncover all of the secrets. Those secrets improve your chances of completing the game sooner. There is no hurry to finish the game so try different directions on every level.
You can achieve everything you have to by going around the various installations in the area killing all of the Stroggs, blowing up generators and taking out the Strogg leader. Destroying the generators and the Black Hole generator alongside the big gun means that the Stroggs are going to be defeated, and killing their leader makes it harder for them to defeat you.
