What video game achievement(s) are you most proud of?

I beat Gears of War 1 on the Insane difficult setting, without having a co-op partner. What about you guys?

@dracula_16: 00 agent in Goldeneye 007 agent.

Completing super Metroid several times and also beating resident evil 4.

Doing 7 day survivor on dead rising in 2007. I had such a pampered childhood as far as material goods go that I had a psp and used it to watch movies while getting the achievement.

Getting level cap in wow was fun too.

Though I missed doing that in dragonflight and shadowlands. I also made it to naxx in wow classic till my guild disbanded.

Beating left for dead on the hardest difficulty. It was pretty tough.

Also there was one for halo odst or reach for firefight mode I can’t remember. It was so freaking hard and took so long. I was super hyped when I got that.
