City of Heroes is going through some tough times this weekend, because the Rikti Invasion is returning, and the world needs your help to overcome!

The looming threat of the Rikti Invasion Force still hangs like a dark pall over Earth. Despite the best efforts of humanity, aggressive Rikti incursions still plague the planet. Advance warning systems indicate the Rikti are massing for attacks on the following dates throughout the year.

Prepare for a desperate battle to save Earth from the Rikti Invasion Force! Aggressive Rikti forces will attack Paragon City and Rogue Isle with increased frequency at any time during the above dates! Some important items to remember about Rikti Invasions:

• When Zones within the cities are under attack, a world-wide alert will be issued by Vanguard. This alert will show up in your Chat window on the System channel, warning you in which zone attack is imminent.
  
• While the invasion is occurring, players do not receive debt while outdoors in an invaded zone.
  
• Those in that zone that do not wish to be at risk of Rikti attack are asked to take shelter immediately. They can do so by leaving the zone, or moving inside buildings or under cover (overpasses, parking garages, etc.).
  
• The combative inhabitants in a zone will move off the streets and to safer locations when a Rikti Invasion takes place.
