SO first off - its XCOM: Enemy Unknown - but its only XCOM: Enemy Unknown release date version - and there is little variation on missions. but there is element from the mod Long war - so if u stall for research u lose, in fact U will lose a lot. so in a sense - its like Dark Souls XCOM: Enemy Unknown and thats both good and bad - the game has improved ALOT from original release. like OMG - release version? NOW THAT was Demon Souls Xcom and U had two broken arms, armed with a toothpick :S For the price a great game but is XCOM: Enemy Unknown but slowly getting on par with X-com 2
