Hazard Master Achievement
Complete the game on the Maximum Hazard difficulty setting.
This is a difficulty related achievement which, will unlock with natural progression.
If you want to run through the game on Hard straight away, enter the following cheat code on the difficulty selection screen ( ). Doing so will unlock the Maximum Hazard difficulty from the very start of the game. This will save you having to play through the game more than once.
The games overall difficulty isn't overly too hard, but there are areas which will frustrate you to no end. If you have already played through the game once on either normal or easy you will at least know what to expect.
If you decided to run through on hard your first time, make sure you take cover as much as possible. If your cursor is read your shot will always hit the enemy even if it is through a wall. You can use this minor glitch to your advantage but be very careful as if the enemy does have a clear shot, you will die.
If there are doorways, walls or solid bits of cover I recommend you use them over destructible objects as you will survive a lot longer and not have to worry about jumping out of cover every so often.
