The Invaders!

Read full description

"Game World View" In the modern 21st century we live in, two advanced alien races from hundreds of thousands of light years away - dogs and cats - discovered the existence of the earth almost simultaneously. However, what surprised them even more, was that the common ancestors of two alien races (dogs and cats) existed on this primitive planet at the same time. Although both are in their primitive forms, a slightly advanced alien race (humans) voluntarily takes good care of the daily life of the ancestors in every possible way. Therefore, in order to compete for the control of the earth's resources, the alien masters are looking for dog and cat servants who are willing to cooperate, and fight for the future of their ancestors (domination of the earth) together! "Game Features" – AR Combat – Players use the mobile phone camera to find enemy ships in the real world, and at the same time destroy enemy ships through real-time shooting battles, so as to send their own ships to achieve the goal of occupying the area. After the occupation is successful, they can also see their own ships cruising in the air in real time! – Turf Wars – When the area occupied by our side is adjacent to the area of ​​the enemy, it can not only weaken the enemy's defense ability but also strengthen our attack ability. Therefore, the more adjacent areas occupied by our side, the weaker the enemy's ship will be. If you can encircle the enemy's area, the chances of defeating a stronger enemy will be greatly increased! – Resource Acquisition – Whether in the area occupied by oneself or allies, players can obtain various resources when they stay in the area, and these resources can also be used to strengthen their own equipment or to strengthen their ships dispatched to occupied territories. – Strengthen Arms – The more territory seized by destroying enemy ships, the higher the player's energy level, and the weapon options that can be used to equip themselves or their ships will increase accordingly. Therefore, continuous fighting, occupying new territories, obtaining territorial resources, and then strengthening the armed forces is the most effective strategy to dominate this planet! - In-App Purchase Options (rechargeable battery) -  Player’s equipment needs to rely on rechargeable batteries to fight. The system provides 10 rechargeable batteries for players to use, but if they can’t wait for the charging time, they can always continue fighting by purchasing them at in-game store. - In-App Purchase Options (automatic tactical drone) -  Player needs to use automatic tactical drones to occupy new territories. The system provides 10 automatic tactical drones for player to use every day. Once they are used up, player has to wait until the next day to occupy the new territory again. If player can't wait for the free spaceship, they can always get new ones immediately by purchasing them at in-game store.
