From their website:
Today we offer a special bonus sneak peek to launch our previews of the upcoming HeroClix release, HALO. We could think of no one better to start off with than Master Chief and Cortana.
Master Chief and Cortana begin the game with a very useful special power, Strategic Positioning; this special power allows Master Chief and Cortana to use both Running Shot and Stealth, meaning not only can they manuever for that critical shot but if positioned correctly they can also hide from retaliatory ranged attacks. Penetrating/Psychic Blast represents the Master Chief and Cortana’s ability to pinpoint their opponent’s weak points, while Outwit allows them to counter a power or ability of their choice.
