Strikes are endgame maps in Sector mode that can only be selected randomly. They
are old Sectors that very powerful Viruses have re-inhabited and are the only source
for Crystals and Legendary Crystals, which are used to buy Augments and Legendary
Items. Strikes fundamentally play out differently compared to other maps by focusing
on enemies dealing lethal damage and having low health pools. Because of this, players
can effectively use defensive stats (which are usually not so useful in Sector) and
they must learn the movements and abilities of the Viruses to efficiently play Strikes.

Strikes offer high EXP and rewards bonus EXP to contributing players.
