Surround and soften enemies, carrying a lot of grenades is very useful doing it this way. Once your team is the size of 6 men always keep two snipers, maxing 2-3 snipes ASAP is top priority. I use Hidden Potential too but then again I'm a savescummer, your mileage may vary :p This game style will have you spend a fortune on hiring and firing rookies, but will leave you with a team with elevated stats. It will decisively change how you play the game because positioning becomes of maximum importance, then again it allows you to easily one-shot enemies even on the higher difficulties. I always use Second Wave, specifically Not Created Equal and Absolutely Critical. Drop PS3T and study the wiki, it's all-around better for knowledge. Alien Containment and South America satellite coverage is a priority. I suggest you go for Classic Ironman, start with Asia to afford losing 3 countries there, but never, ever allow losing a country in South America. Study this guide, it concerns Impossible difficulty but applies to Classic just as well. How you beat the game is always satellite spam.
Litanja I think I might've posted on XCOM before but since Kav's not around and I'm already up :p.
