10 Shocking Video Game Betrayals That Scarred You For Life

4. Wrex - Mass Effect

You can only really call this a 'betrayal' if you go against Wrex during this altercation on Virmire, but either way it's a shocking moment, as up until this point the angry Krogan was on his way to becoming a firm fan favourite.

Things start to get supremely tetchy when Wrex discovers that the genocidal Genophage virus can actually be 'cured' by using the technology that villain Saren has inside the facility you're heading towards, but the reality is that it would do far more damage than good in the long run.

Suddenly, you're both eyeing each other up through pistol crosshairs, with the option to reason with him, shoot or berate his hair-trigger all up for the taking.

Wrex can make appearances in the following two games depending on how this altercation goes down, but the moment you realise it's actually happening and can genuinely choose to execute a main character in the process, is pretty incredible.
