STREET FIGHTER IV

There are 20 levels to complete on the Normal Survival challenge. You will need to get the necessary quota of wins in each one, to "gold crown" it. Once you've earned gold on all levels, the achievement will unlock.

The fights in each level must be completed with one character, within one health bar without losing a match. Each win will give you a small boost to your health bar, so it's ok to take minor damage in some fights.

You can either pick a character you're very good at and play defensively (I did this with Sagat), or if you're having trouble, use Zangief and mash his lariat moves. There's some excellent info about this technique on the forum: 'Giefing it up (A guide for using Zangief for achievements).

Note that while most of these levels are straightforward, round 19 requires you to use no special moves - it's recommended you pick Akuma and use his standing HK for this level.

If you need a full list of tactics, required win quotas, and level rosters, there's a very in depth guide on GamqFaqs by "siky" which can be found here: http://www.gamefaqs.com/xbox360/943712-street-fighter-iv/faq....
