Marv dealt the killing blow to that Colossus and the group left for the next realm with the artifact they had found. (You still have the artifact by the way Marv if you forgot)
The next realm turned out to be the group returning to Earth. The group had been called back due to a Colossus finally breaking its way into earth.
After a chance to regain their strength, the group was taken by helicopter to where the Colossus was along with the Commander. They are now fighting the Colossus on top of some rooftops, you should be able to check the last page for fight details.

Romans 8:31 What, then, shall we say in response to this? If God is for us, who can be against us?
1 Corinthians 13:1-3 If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but do not have love, I am nothing. If I give all I possess to the poor and give over my body to hardship that I may boast, but do not have love, I gain nothing.
