The roster gets inflated by some surprising guests.

NetherReam and WB revealed the line-up of new heroes that will join the pack in Injustice 2. The trailer was part of a Gamescom showing. Take a look:

It doesn’t feature any actual gameplay but we now know that we’ll be able to try out the Mortal Kombat alumni Raiden, Black Manta, and most surprisingly Hellboy.

The pack goes on sale on September 12 and will be available for free to those who bought Injustice 2 Ultimate Edition. For everyone else, we can expect similar pricing as with Fighter Pack 1 – $20 for the whole thing or $6 for each individual fighter.
