C'est xcom 1 en mieux donc une référence du tactical rpg sur PC

Personally i never played any of the previous games but despite that i enjoyed some parts of the story. Generally the gameplay relies on you actually using your brain when putting your soldiers in a good position otherwise you'll lose them, ontop of managing your resources which are actually pretty easy to lose due to bad investing. As for the 'Percentages' i am not entirely sure if they're accurate , i mean 94 misses? Personally if that happens to you , get the lottery.
