When you've played games for a long time, you'll start to expect certain things.
For example, if you're playing a platformer, there's probably going to be a snow level. If you're playing an RPG, you know they're probably going to end up fighting literally God at the end.
As gamers, we tend to expect things to happen in a certain way, and for those games that do implement something new, we start to learn their new mechanics through hours of gameplay, and by hour 20, you should be well versed in what a title has to offer.
That is, of course, until the game throws you completely for a loop by using everything you've learned so far either in that title or through other games against you.
These can come out of absolutely nowhere; you're playing the game, thinking you've got everything down and now what's coming next, and - BAM - it smacks you straight in the face with the unexpected.
11. Tomb Raider 2 - Befriend The Monks Or Die
There are a few rules in the original Tomb Raider games.
1) Walk up to the edge of a ledge. Hop backwards, run forwards and hold square to do a running leap.
2) Make sure you do a pointless handstand when rising from a ledge.
3) If something is moving, it's probably hostile and it needs to die by you shooting it.
Number 3, in particular, is a staple of the Tomb Raider series. From fellow humans to yetis to an absolutely terrifying T-Rex, whenever Lara encounters something, she generally puts it down with her shooting irons.
Imagine our surprise when we got to Tomb Raider 2's Tibetan monastery levels, where, without warning, it started to introduce friendly monks. We're pretty sure absolutely everyone is guilty of blasting these poor, innocent warrior monks away without mercy, not realising they are, in fact, friendly.
If you don't shoot them, they'll even help you out in a fight! However, if you do shoot at them, they ain't happy about it, and they'll become aggroed and make the whole level that much harder than it needs to be.
