All the cool materials, upgrades, weapons and technology featured in XCOM: Enemy Unknown's expansion - Enemy Within such as MELD and Mech Troopers will not be featured in XCOM 2. As detailed by Lead Producer at Firaxis Games, Garth DeAngelis, the now 'canon' post-Impossible Ironman outcome seemed much bleaker than we earlier imagined.
"The scenario we are looking at (when we develop XCOM 2) was that the Aliens hit hard and XCOM had no chance early on in the game. They never progressed that much to even research such technology" he explained.
"This is also the reason they are still stuck with bullets (ballistics) as opposed to plasma or laser weapons as seen in the trailers and gameplay videos." he added.
XCOM 2 is set to hit PC November this year. No news on whether it will hit other platforms as of this moment. For more news on XCOM 2 and more out of E3, stay tuned to IGN.
