Crysis 2 Remastered (EP)

Cannot be missed, you get this cheevo once you finished the story, no matter what level.

I have two different advices for you:

1. Play immediately on Supersoldier level. That way you can score two extra cheevos at the same time (this one, for veteran level and the one for supersoldier level).

2. First play on Recruit to collect a much nanosuit catalyst credits and buy all the nanosuit upgrades to make your life easier during your supersoldier run. (these credits and your armour unlocks will stay with you).

However, I played on Supersoldier from the start with the same Crysis 1 method (cloak, aim, armor mode, shoot, back in cloak) and never really missed the upgrades. Yes it was easier once I got them but it wasn't necessary. It saved me quite some time ;-).

One extra tip: in the final level, right at the very end you will have to fight 4 Ceph that can cloak and (on Supersoldier) are quite bullet spongy. I didn't have it but my advice is to save for the cloak tracker upgrade and buy it if you need.
Others are: nano recharge, cloak enhance and mobility enhance. It will make you fly through the levels undetected.
