Crytek has made an interesting announcement concerning Crysis 3 and it's opening weekend. We can have up to 72 hours of double XP if we do the following.
Crytek wants us to share this facebook post as much as possible. Every 60 shares from now until February 14 will grant us 1 hour of Double XP. So, we'll need exactly 4,320 shares to get the full 72 hours. Also, at 1,000 shares Crytek will unlock a mystery item too. You can also add an additional 6 hours by retweeting this tweet. It has already received more than 300 but who knows? Maybe we'll get even more if we exceed their expectations.
The double XP will really come in handy for players who want to use the Predator Bow. In the beta, after you reach level 10, you must then reboot your suit, which is like prestiging, and then rank up to level 5 again to unlock the bow. I imagine in the full game it would be a lot harder to unlock, the Double XP could really help.
