A swarm is an event where players compete to destroy the most invading alien ships. The event takes place every 4 hours and lasts for 15 minutes. It takes place in Omnicron sector and the invading ships are usually Insectizen but occasionally hordes of miniscule Justin Beiber's swarm the screen. Oh what fun to blast their oddly symmetrical faces out of the sky.
At the end of the event the participating players are awarded with Fame and money. The amount depends on both the place you take and the number of total participants (the minimum reward is 20k cash and 2 fame). First place will also recieve one random ship component (it can be just about anything, though no blueprints have been seen as of yet).
