Explore the galaxy and carve out your own destiny in a 3D MMORPG. This truly cross-platform game enables thousands of players to interact as the pilots of spaceships in a vast online universe. Players may build their characters in any direction they desire, becoming rich captains of industry, military heroes, or outlaws. A fast-paced, realtime "twitch" style combat model gives intense action, coupled with the backdrop of RPG gameplay in a massive online galaxy. Three major player factions form a delicate balance of power, with several NPC sub-factions creating situations of economic struggle, political intrigue and conflict. The completely persistent universe and detailed storyline add to the depth of immersion, resulting in a unique online experience. Support for multiple platforms across desktop and mobile, all of which play together in a single unified game world. Pilots may seamlessly switch from one platform to another. The game supports Xbox, PS4 and MFi game controllers, and features cross-platform voice chat, as well as voice-recognition text chat for hands-free typing, text-to-speech for reading mission and other game updates, and many other features. Although the game can be played quite casually, this is a "real" PC-grade MMORPG, and is not a watered-down "mobile" game experience. Our native iOS version has exactly the same capabilities as the PC versions, with a different interface. The game is updated frequently, usually every week or two, with the developers and userbase actively discussing the future of the game on the Vendetta Online forums. Many frequent updates are server-side and will not result in a visible "iOS app" update. Vendetta Online offers three distinct access tiers: 1) Free, where you pay no money at all, and may earn "Crystal" currency through your gameplay, and spend it on certain higher-end ships and equipment. There are no level caps, and you may use your account to play on any other platform (like the Mac). Some high-level content is not available to the Freemium tier, like assembly of player-constructed Capital Ships. It takes many months to build these endgame assets, and Freemium players may work towards those goals, but not complete them. 2) Lite, where you basically subscribe for $1/month, gain the ability to earn 50% more crystal per day, and may build and own the Goliath-class Capital Ship. This ship may also be made "Enduring", causing it to store a permanent record of the ship's usage and history in the game, and making it into a trade-able part of the world. 3) Premium, where you no longer require "Crystal" currency, or even see it, and you only play the game itself the way it was originally intended. Trident-class Capital Ships are available. Lite and Premium levels are available via In App Purchase, as well as blocks of Crystal. If you have any problems or concerns, please contact us via email, or (preferred) by creating a Support Ticket on the game website (more secure, and it proves the account in question is yours). We are a small indie developer, but we respond quickly. Leaving reviews is not a very effective way to reach us about problems. If you are looking to try out your game iOS account on another platform, be sure to "Convert" your account with email verification. You can do this in the Options area, after logging into the game. -- LEGAL -- Duration and price of each subscription is displayed inside Vendetta Online's storefront, updated at the time of purchase. 1, 3, 6, and 12 month subscription lengths are available for both Premium and Lite modes. Payment will be charged to your iTunes account at confirmation of purchase. Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period. Subscriptions and auto-renewal can be managed/turned off in your App Store Account Settings. End User Licensing Agreement: https://www.vendetta-online.com/h/eula.html
