To get the Operation Iceberg you have to play the game on April 1st (you can change your computer time if you want). More of an Easter egg than a trophy but still very cool.
If you find it hard to use the heavy cannon (The standard turret) Then I suggest using a dual Machine gun, remote missile and some buffs. It is much easier to aim and so far I have been able to do everything.
Strange I have played this game twice now and been sure to search everywhere. the first time I only found 44 sprite droppings. Second time I found 47. The extras were in places I know for a fact I searched the first time. Does anyone know why this is? Great game tho 5/5 in my books
Look people if you earn an achievement click on the "Report missing achievement" button at the bottom of the Achievements tab. Follow the instructions and Kong will give you the achievement. They are really good at this and it is always done within a couple of days. Posting a comment here will in no way help you.
This game is pretty good. Very in-depth combat system and lots of choices in weapons/powers etc. My only complaint is that it gets very repetitive very quickly. Maybe shorter would be better in this case.
