Injustice 2 - Announce Trailer | PS4
Anyway, the first tweet appears to show Supergirl in a very dark outfit landing amongst a crater of rubble. Apparently, a huge, devastating, explosive battle has just taken place and the city is left in ruins. This clip seems to come from a cinematic and not actual in-game play given that there are no stages in _injustice 2 _(that have been revealed so far) that look like what"s featured in the clip and Supergirl appears to be in a dark, gritty looking outfit.
