At last we have the great Duke Nukem Forever. The game that all Duke Nukem fans have been waiting for, the game that’s been in development for more than twelve years! It’s been a long wait, but it has been worth every single passing day. There are a total of 50 achievements and are fairly straightforward. Most of them can be obtained simply by playing, but some require more attention.
Step #1: Campaign on Casual
This will allow you to easily clear the campaign and familiarize yourself with the environments and enemy spawns. You should aim to get 47 achievements. Collect all of the collectibles on this run as there is no way of tracking the collectibles other than the EGO points. The EGO points are the most important of these as they increase Duke's health which will be essential for Step #3 the Campaign on Insane. This run will net you the boss kills and the casual difficulty achievements. Get all the weapon specified kills, find the helmets, listen to the phone messages and unlock the miscellaneous achievements such as: stealing some poo, writing on a board, looking through a whole calendar, etc. Also get the mini game wins and high scores in alien abortion, pinball, and air hockey. Keep the golden gun on you through all chapters for “Gunslinger”. Achievements missed can be earned in Step #2 or the Insane playthrough.
Step #2 (Optional): Mission Select
If you failed to max out your EGO it is advised to chapter select on Casual as you will need health to survive Insane difficulty. Your goal is to complete any collectibles, kills or miscellaneous achievements that you missed on the Casual playthrough. It is wise to unlock all of the 47 achievements before starting your insane playthrough.
Step #3: Campaign on Insane
With Insane now unlocked this will be the next chosen difficulty. This run is quite challenging as the enemies will hit hard and there are extreme difficulty spikes. Keep to cover, always be either strafing or back-peddling to avoid fire or charging enemies. Always look for the weapons caches and save items (beer, steroids and Holo-Duke) for tough situations. If you have cleared all 47 of the achievements this Insane run will unlock the last 3 achievements you for beating the game on medium, hard, and insane.
Step #4: Mop Up
If you are still missing kills or miscellaneous achievements it is possible to chapter select for these. This also includes the golden gun which is given at the beginning of each chapter select though there is no way of tracking which levels have been done. If this list includes collectibles you can still chapter select but be sure that you have made it to a checkpoint as it will not save the data. Note: This is not possible for “Party Animal” and “Pescaphobe”.
Well, it's been a long wait, and a great game to have waited for. If you’d like, you can try out the multiplayer, but this game's strong point is definitely it's campaign.
