Worms 2: Armageddon

You have a Jet Pack here, and will need to execute some quick flying in order to dodge the tracking of the Sentry Guns. The only crates that are guarded by Sentry Guns in this mission are the two crates that are located towards the bottom-middle of the screen and two located at the far right, so you shouldn’t have any problems collecting the others. Please note, that although you cannot take any Sentry Gun damage here, you CAN take Mine damage, so don’t worry if this happens. I can confirm that the explosion from a Mine can also destroy a crate; however this will count as collected and will not disrupt your trophy progress.

Once you reach the bottom-middle of the screen, you’ll see that there are two crates located either side of the Sentry Gun in the ditch. Starting with the one on the left, slowly inch yourself towards the crate and collect it. You will hear the Sentry Gun starting to track you, so instantly retreat and hide in the small ditch located just underneath this crate and you will not be hit. See the picture below for an illustrated explanation:
 

For the crate over to the right, don’t be tempted to fly out into the Sentry Gun’s sight, as this is a very risky move that will most likely end in disaster. Instead, take the path that leads upwards and over the Sentry Gun and make your way over to the second crate this way. There’s a chance that you may accidentally activate the Mine here which in turn will destroy the crate. However, don’t worry if this happens, because as previously stated, it will still count as a crate collection even though you didn’t technically obtain it.

Finally, for the two crates located at the far right of the screen, you’ll have to navigate through the land and drop down, passing the sight of two Sentry Guns. This shouldn’t prove to be too difficult, because as long as you continue to descend with your Jet Pack and don’t slow down, then the Sentries cannot get a proper lock on you and thus will not be able to shoot.
