eXtreme Edition
On July 15, 2010, an alternative version of Mabinogi Heroes was announced for Korea. It is known as the eXtreme Edition, and often referred to as Mabinogi Heroes XE and abbreviated MHXE. The game itself is the same but the eXtreme Edition offers upgraded combat. Based on existing high-quality movements in Mabinogi: Heroes, Mabinogi: Heroes XE will present splendid and unrestrained movements more in line with the public's taste. Moreover, it will start off from a new server instead of being an update for the original Mabinogi: Heroes. Players can choose the normal server or XE server according to their interests. Currently, characters in the two different servers cannot be shared, but character transfer service will be provided in the future.

Differences between the two versions
Compared with Mabinogi: Heroes, Mabinogi: Heroes XE has the following major differences:

A jumping system has been added. With the help of it, players can easily jump over small monsters and traps. Players will be able to strike monsters to the sky. In the game, players can take specific actions to hit the enemy up into the sky and launch combo attacks. A combo system will be added. If players succeed in attacking the enemy continuously without being interrupted, they will gain combo points. When their combo points meet a high requirement, they can use a designated skill to deal extra damage.

Additionally, the XE Version differs from Mabinogi: Heroes in faster movement speed and higher damage of common attacks.

Korean Release
Mabinogi Heroes eXtreme Edition debuted in Korea on July 22, 2010.

GamersFirst s'offre Fallen Earth, le MMO adopte un modèle Free to Play
 
On le supposait et l'information se confirme aujourd'hui : GamersFirst reprend l'exploitation du MMO post-apocalyptique Fallen Earth et fait évoluer son modèle économique vers le Free to Play (presque).
 
Nous l'évoquions récemment : après avoir déjà repris l'exploitation d'All Points Bulletin (suite à la faillite de Real Time Worlds), GamersFirst s'intéresse maintenant au MMO post-apocalyptique Fallen Earth.
Aujourd'hui, au terme d'une conférence d'actionnaires réunissant le premier cercle de GamersFirst et Marie Croall, lead designer du MMO (et dont les bons mots sont rapportés par le blog Massively), GamersFirst reprend officiellement l'exploitation de Fallen Earth (le design reste à la charge de l'équipe de développement originale qui devient une « extension » de GamersFirst) et fait évoluer son modèle économique vers le Free to Play.
 
Cette évolution de modèle économique verrait l'apparition de quatre « offres » plus ou moins onéreuses et proposant plus ou moins de contenus.
 
    L'offre « Free » devrait permettre de jouer gratuitement à la version de base du jeu, sans limite de temps ni de contenu mais ne permettant pas de gagner de « points de récompenses » ;
    L'offre « silver » (dont le prix serait inférieur au montant actuel de l'abonnement mensuel) donne également accès à l'ensemble du jeu, mais en intégrant des gains d'expérience améliorés ;
    L'offre « gold » (dont le prix serait similaire à l'abonnement mensuel actuel - soit environ 15 dollars) octroie des points de récompense permettant d'acquérir des objets dans la boutique de jeu et divers bonus chaque mois. L'exploitant souligne que les abonnés actuels « obtiendront donc plus pour le même prix » ;
    L'offre « VIP » (dont le prix devrait être légèrement supérieur à l'abonnement actuel) devrait permettre de partager ses « bonus VIP » avec d'autres joueurs (le joueur VIP disposera d'une « aura VIP » octroyant des bonu VIP à l'ensemble des joueurs d'un groupe, peu importe l'offre à laquelle ils souscrivent). Et l'aura est cumulable, donc plusieurs membres VIP dans un groupe permettent une multiplication des bonus.
 
Plusieurs détails restent néanmoins encore à finaliser (comme le contenu précis de la boutique ou le montant exact de chacune des offres) et à ce jour, on ignore encore quand cette offre « Free to Play » sera disponible. Mais gageons que nous en apprendrons plus prochainement et que le changement de modèle économique sera susceptible d'attirer de nouveaux joueurs vers Fallen Earth.

Zombie Studios announced that the sequel to Blacklight: Tango Down will be free. It will use Unreal Engine 3 and will contain playable mechs in the gunfights. The name should be BlackLight: Retribution.
