No base invasions. No fatigue. No suicide bombing. I can only throw ONE grenade in a mission per unit (unless got extra skill). WTF pathing. ONE base only. No Alien grenades. Everyone sounds like American and every male looks like Zangeif. Fixed shooting chances. Chyrsallid is not that scary anymore. All aliens will destroy their own weapons when they die, you MUST stun them to get the whole equipment. Cannot change equipment anymore , no inventory system. Starting game cannot field multiple rookies as there is only 4 units. You can upgrade to max 6 later but must build facilities first (I might be wrong on the max squad size).

Aliens dont panic anymore, just retreat and then when you come close enough they pop out and shoot you again. A highly difficult mission means just going through a straight path map with minimal cover. lol

You cannot recruit engineers and scientist anymore, MUST go through missions to get them. Problem is like 3 terror sites at once, you WILL take reputation hit for the other 2. wtf. Interceptors only can attack units in their region and you must get aircrafts for every country that is listed.
