Jurassic: The Hunted

The easiest place to do this is the first fortification area which is in level 3 Sinking Feeling. I just kept moving counter clockwise and shooting the dinos thru the windows and pressing down on the D-pad to fully repair the window before moving to the next one (you can shoot and repair at the same time). You will have plenty of time as long as you don't hesitate to long. If there is no dino at the window don't stop and move on to the next one.

Once you get the cue to move on don't forget to repair all the windows before opening the gate. You will get another achievement for that also.

If you find this solution helpful please remember to vote positive.

Thank you and Good Luck!

got this at the third fortification objective later in the game, can be done at any of the fortification levels using level select if needed.

i was struggling to get this achievement until i realized one thing.
the dinosaurs come in waves.

with that in mind go around killing the dinosaurs like usual as fast as possible, BUT leave ONE dino at the window and keep repairing it, going and repairing all the other windows one at a time while babysitting the dino window until they are all fixed, then kill the dino at the window and start the next "round".

got it first try after learning this, alot easier than trying to shoot continuously and gives you a chance to reload.
