Infinite Warfare and Modern Warfare may be set in the same universe, if this tweet from Twitter user @Blade_151 is anything to go by.
The picture shows that Retribution's class is called SWC-141, and in Modern Warfare the Task Force 141 was the anti-terrorism unit in the game. SWC-141 took the name, therefore, to remember Task Force 141's rescue of Boris Vorshevesky in Modern Warfare 3.
Do you like this little detail slipped into Infinite Warfare?
