Introduction:
Crysis is the first of a Science fiction first person shooter trilogy. Yes, I said trilogy because Crytek has confirmed this. This game is very different from the second one, there is no upgrading or new game plus for those who are wondering. You get weapon attachments such as silencer, grenade launcher, and scopes. You are looking at around 7 hours or so on your first playthrough, going for miscellaneous achievements, such as picking up turtles and throwing chickens at people till they die.
This game integrates partial free roam. Main objectives will be in green while secondary will appear in yellow, which you can choose to complete or leave. You can also choose your path to your objectives. Follow the road, climb the mountain, or go through the forest. For your Delta playthrough, it will take 6-12 hours. Depending how familiar you are with this game and FPS's. That's why I insist you play on the easiest settings first. Knowing shortcuts and being familiar with the island can make all the difference. Other then that have fun and enjoy the story!
Step 1: Easy Playthrough
Start your game and play it on the easiest setting. While your playing go for your extra achievements. Follow my guide for better locations and information for each specific achievements. Start throwing people, pick up an animal, chuck items at enemies etc. Make sure you kill someone with every new weapon you find.
Attachments transfer to all weapons once you find it once. Make sure you do EVERY secondary mission when asked and pay attention to your radar for when they pop up. Once they do, press back button occasionally to check your objectives list. Other than that it's fairy simple. Don't fight when outnumbered by more than 4 or 5 enemies from close range, they will tear you up. So try and find alternate paths with less people. You should complete this in around 7 hours with 820G once you've completed it.
Step 2: Delta Playthrough
Now to start on Delta difficulty. You should have a pretty good idea of how the game plays, where you have to go, and what you can skip. Now if you have played this game before on PC or you are just pro like that. Then skip step 1 and start on Delta instead.
Make sure you change your difficulty in the options at the main menu, and start new game and select Delta again, just in case. Now this difficulty is hard, but not as bad if you play smart. Also, don't expect to be able to cloak your way through this like in Crysis 2. There are no upgrades, which means no cloak enhance. You run out very quickly.
Step 3: Clean up
If your still missing anything, which is highly unlikely. Then just go back into mission select and choose replay mission. All your progress towards a specific achievement will carry over as long as you DON'T start a new game. Once you start a new game, everything will reset for that campaign. Why I insist you play on easiest settings first. Getting everything on Delta will be much more challenging.
