Blindfold Games are entertainment apps provided as a service to the visually impaired community by Objective Ed. Your in-app upgrades pay for the development and support of these games.  Invaders is an fully accessible audio game, inspired by the video game Space Invaders. The objective is to shoot all of the invaders before they land on your planet. There are several rows of space ships, that move left and right, starting at the top of the playing field, furthest from the home button. The ships move back and forth, heading down towards your planet. You must shoot them, and avoid being shot. The more invaders you shoot, the higher you score. The more times you get shot, the lower your health score. When you shoot all the invaders, you move on to the next level. There are several games of varying difficulty, and varying number of levels. Each level is harder than the prior level. Invaders was suggested by several blind gamers who enjoyed Blindfold Breakout. The game comes with coins; you need one coin to play. More coins are available as an in-app upgrade.

IMPORTANT: THIS IS AN AUDIOGAME Zero Hour Assault is played entirely by sound and is designed for the blind and visually impaired community. Everything is spoken by the game's own voice or through VoiceOver, so you never need to look at the screen. It works with VoiceOver on or off; with VoiceOver on, your gestures go straight to the game. The screen shows menus and messages in large text, and during play the gestures that work at that moment as a map of the screen, your map, your hands and the last spoken message. Please put on headphones for the best experience. Dive into intense, non-stop combat in Zero Hour Assault, an online first-person shooter where strategy, skill and teamwork are the keys to survival, whether you hunt alone or with your team. Fight on your terms: drop into a battle royale where the safe zone keeps shrinking, plant or defuse the spike in Search and Destroy, survive zombie hordes with your team, or prove yourself in duels with only snipers, swords or your bare fists. Key Features: 22 Match Modes: Nine new modes (Battle Royale, Search and Destroy, Team Deathmatch, Kill Confirmed, Hardpoint, Gun Game, Infected, Blackout and Squad Rounds), where everyone gets the same equipment, plus thirteen classic modes such as Capture the Flag, Zombie Survival and Knife Fight. Bots can fill empty seats in most modes. Freedom Fight in Brackenford: Parachute into Brackenford, an open city where the fight never stops. Enter about 60 buildings, climb stairs to the roofs, shatter windows, loot chests, and race for airdrops, control points and helicopter extractions while red zones push you around the map. Build and Defend Your Base: Form a group with friends, get a walled base on the freedom fight map, store loot in its chests, and defend your turf from rival players. If all the bases of your group are destroyed, your group is gone forever! Deep Tactical Gameplay: Aim up and down, land headshots and leg shots, carry a weapon in each hand, fit a silencer, and use a weapon melee attack to disarm and down your foes. Walls stop every bullet. In freedom fight and several modes a fallen fighter is knocked down instead of killed, and friends or teammates can lift them back up before they bleed out. Extensive Arsenal & Gadgets: Rifles, shotguns, pistols, sniper rifles, knives, swords and explosives, plus motors and bikes. Become invisible with the Invisibility Shield, lay traps with TM62 mines, create cover with deployable Barricades, or track your enemies with the Spatial Amplifier. Fair Progression & Rewards: Earn zero tokens by playing and spend them in the store. Every character has the same health, speed and damage; your character is your voice and identity. Climb the rankings and the season pass, unlock titles and cosmetics, complete missions and daily events, and spend event points in the event store. Free to Play: Optional in-app purchases offer zero token packs, a paid account, character voices, cosmetics and other extras. A paid account adds comfort and cosmetics, never combat power. All purchases are made inside the app. Integrated Voice Chat: Coordinate with your team using positional audio to hear nearby allies, or use community voice chat to talk with your whole community across the game, regardless of distance. Your Language: Play in English, Arabic, Spanish, Portuguese or Turkish, with more languages translated by players. Chat has 27 language channels and can translate messages. Made for Touch: On iPhone and iPad you play with touch gestures, and "View touch screen gestures" in the main menu explains every one. iPhone and iPad use the mobile server, built for touch play. Windows players have a separate server on purpose, to keep the game fair for touch players; choose it with "choose server" in the main menu if you want to face them. The battlefield is calling. Gear up, pick your character, and prove your worth. Are you ready for Zero Hour Assault?
