There has been a bit of confusion regarding the April side-quest in Marvel Contest of Champions, so let’s break down how it actually works.
First off, you need to decide whether to pledge to The Ancient One for rank-up materials or Apocalypse for crystal shards. View the full rewards available here.
After you select your Faction, you will fight for that side for the next two weeks.
Week 1 will be available from April 1 at 1pm EST to April 15 at 1pm EST.
Week 2 will be available from April 8 at 1pm EST to April 15 at 1pm EST.
After you complete Weeks 1 & 2, you will have the two week total for rewards as listed in the forum post.
There has been talk about the Week 1 Quest resetting in 7 days. This is not correct, as there is a new chapter being released each week.
Weeks 1 & 2 expire on Wednesday, April 15 at 1pm EST, meaning you have to do them by this date or you will miss out on the rewards. The Faction Selector will then reappear, allowing you to continue on with your previous Faction or Double Cross them and join the other side. There appears to be no loyalty bonus for sticking with your Faction, however, if you do change sides your objectives will change, so keep that in mind.
Week 3 will be available from April 15 at 1pm EST to April 29 at 1pm EST.
Week 4 will be available from April 22 at 1pm EST to April 29 at 1pm EST.
The combined rewards for Weeks 3 and 4 are the same as the combined rewards for Weeks 1 and 2.
Hope that is helpful. Which side did you choose, and are you going to double cross your Faction on April 15? Let me know in the comments.
