For the most part, these videos are helpful, even if they are out of date. However, toward the later summer levels, the level design has changed, and the method you need to get three stars has also changed.

The summer levels are the first ones you play through and there are a total of 20 of them. There are 2 types of levels in the summer ones: clear the area and turn the scientist. In the clear the area ones your mission is to just turn everyone on the screen into zombie to complete the level. In the turn the scientist ones, your goal is to reach the scientist without getting killed by the enhanced soldiers by playing stealthy.

Once you finish the final level in the summer pack, the trophy will pop.
