RPG Mod

Mit dem Code auf dieser Seite kann man mit seinen Helden wie in einem RPG Spiel Erfahrung sammeln und im Level aufsteigen. Durch einen Levelaufstieg bekommen die Helden mehr Gesundheitspunkte, mehr Angriff und mehr Verteidigung. Außerdem können sie schneller ihre Spezialfähigkeiten einsetzen. Diese Mod wurde für den MP Modus entwickelt, funktioniert aber durchaus auch im Singleplayer.

Wird ein Held markiert, öffnet sich über dem normalen Selektionsmenü ein weiteres Infofenster, in dem das aktuelle Level, die gesammelte Erfahrung (in Prozent bis zum nächsten Level), die Aktionspunkte sowie die vorhandenen Items zu sehen sind.

Erfahrung sammelt ein Held, wenn in seiner Nähe eine feindliche Einheit durch die eigenen Einheiten vernichtet wird. Die Anzahl der Erfahrungspunkte richtet sich nach dem Typ des Gegners. Ein Hauptmann bringt z.B. mehr Erfahrung als ein einfacher Soldat. Gebäude bringen keine Erfahrung. Feindliche Helden geben je nach Level am meisten Erfahrungspunkte.

Befindet sich mehr als ein eigener Held in Reichweite, so wird die gewonnene Erfahrung zu gleichen Teilen auf alle Helden aufgeteilt. Tipp: Man kann einen schwachen Helden also schneller Erfahrung sammeln, wenn man die starken Helden aus den Kämpfen heraushält.

Wenn ein Held genug Erfahrung gesammelt hat, steigt er eine Stufe auf. Die Erfahrung die dafür benötigt wird, steigt von Level zu Level. Mit anderen Worten wird ein Held mit niedrigem Level schneller aufsteigen, als ein Held mit hohem Level. Pro Level erhöht sich die Gesundheit, der Angriff, die Verteidigung und die Aktionspunkte.

Der Einsatz der Spezialfähigkeiten hat sich gegenüber dem Originalspiel geändert. Die Fähigkeiten haben keinen Cooldown mehr, sondern verbrauchen die sogenannten Aktionspunkte. Aktionspunkte regenerieren sich (ähnlich wie die Gesundheit) mit der Zeit von selbst.

Helden können nun Gegenstände tragen, die in speziellen Schatzkisten zu finden sind. Das können z.B. Heiltränke oder Rüstungen sein. Im SP Modus könnten die Helden auch Schlüssel oder andere Questgegenstände tragen. Leider gibt es noch keine Möglichkeit Items beliebig einzusetzen oder wegzuwerfen. Ein Heiltrank müsste also automatisch eingesetzt werden, wenn die Gesundheit des Helden sehr schwach ist.

Im Multiplayer können den Helden über die S5Tools eigene Namen gegeben werden, die dann bei Info-Messages bei allen Spielern angezeigt werden.
