Video Game Tips/Easter Eggs/Cheats

This topic is so that us gamers can share any tips or easter eggs or anything which we have discovered in games on 360/Wii/Ps3/Pc

This is not where you post things like cheat codes or things you can find anywhere, post your own personal findings in games which have most likely not been discovered before. Or just give useful advice. (it can be completely miscellaneous).
And it can be about any game you like.

Here's the first contribution:

JUST CAUSE 2 (360/PS3/PC)

How to holster your gun:
You may have noticed that Rico (Scorpio) never seems to put away his weapons. They're in his hands nearly constantly. The only time he puts them away is when you are performing actions like sprinting, but then he takes them out again afterwards.
I discovered a way to make him holster them permenantly (until you take them out again).
Press and hold the sprint button for just about a second. Hold it long enough so that he doesn't roll, but not long enough that he starts to sprint. It may take a couple of tries to get right but it's very easy.
That is it. You now have a holstered weapon.

Thank you, because being able to holster my gun significantly improves my gameplay experience.

In New Vegas talk to the assistant of the dude who gives you the quest of going into the vault with the plant people and you can repeatedly do a speech challenge for her until you get the achievement and in game exp bonus.

You're welcome.

No seriously, I was just giving an example. It's something that you're not supposed to be able to do.
