These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
That One Level: The prison break level In the second game. Finding the prisoners is easy; getting to them is another story. The entire base is loaded with plenty of strategically planted, heavy hitting turrets that can take a licking and keep on kicking, and the thick barriers surrounding them means you usually have to put yourself right in their line of fire in order to shoot them. The m1 barely stands a chance against them, and they will mop the floor with the Mototank. Making matters worse is that this is a fairly early level in the game, so it can easily catch you off guard.
