Crystal Dynamics has come up with a promotion that will concide with the Playstation 4 release of "Rise of the Tomb Raider: 20 Year Celebration" next week.

The developer is giving away a whopping 100,000 in-game credit bonus, which is used to buy Expedition Card Packs in the game, when "Rise of the Tomb Raider" launches next week. All the players need to do is login anytime between Oct. 11 and Oct. 18, 11:59 PST to qualify.

Players only need to have internet connection to log into the server. The good news is everyone who has a copy of "Rise of the Tomb Raider," regardless of platform, is eligible for the 100,000 credit giveaway.

"This is our way of saying thank you to each and every one of our fans," the developer wrote on the "Tomb Raider" Tumblr blog, "whether you've been with us for days, months, years, or decades!"

These credits are used to purchase Expedition Card Packs, which in turn grants extra game modes such as the new co-op endurance and "Lara's Nightmare." Some cards also grant Lara different special advantages, while some are meant to be humorous, such as the Big Head card. More details about the Expedition Cards can be found here.

The new PS4 version will not just be a simple port from the previous launch. The '20 Year Celebration' edition will have a new story mode called "Blood Ties," which will allow players to explore the iconic Croft Manor and discover its secrets.

For those who are looking for all out action, there will still be combat in the Croft Manor, in the form of another mode "Lara's Nightmare. In this mode, Lara would have to fend off an undead invasion.

"Rise of the Tomb Raider: 20 Year Celebration" will be released on PS4 this October 11 and will include the base game plus all the already released DLC's "Baba Yaga: The Temple of the Witch" and "Cold Darkness Awakened."
