Introduction
The game mainly is about two players facing a bunch of incoming missiles. When a player hits a missile, one life will be deducted from him or her. As time goes on, the frequency of incoming missiles spawning will gradually increase by 0. 05 % every second. When it reaches the frequency of spawning 6 missiles per second, the frequency will no longer increase (lag and skill issues). The players’ target is to survive as long as they could with initially 3 lives, while competing for a longer survival time. They can make use of rockets and different modifiers to help them stay alive.
Basic Controls
Player 1 uses WASD keys to move the airplane and uses key E to fire a rocket
Player 2 uses ARROW keys to move the airplane and uses SPACE bar to fire a rocket
Modifiers
All modifiers will spawn together like the missiles in random positions and times. Some spawn more frequently while some are relatively rare. Players obtain them by making contact with them and collect them. The following is the list of all modifiers and their functions (in rarity order):
Cloud : They spawn the most frequently (every second) and technically serves no purpose. However, some missiles may hide under the clouds to make them undetectable, so watch out.
Mega Supplement : They spawn every 7 - 10 seconds. Once obtained, the next rocket fired by the player will have a 20% larger hitbox. Additionally, if the rocket hits an incoming missile, the player will gain 1 additional life.
Life Booster : They spawn every 10 - 20 seconds. Once obtained, the player will instantly heal itself 1 life.
Silver Bullet : They spawn every 13 - 20 seconds. Once obtained, the next rocket fired by the player will pierce through all missiles.
Shield Protector : They spawn every 17 - 27 seconds. Once obtained, the player will be immune for the next 3 incoming missiles hit.
Signs
You will notice some texts hovering on your airplane when you fly. These indications can clearly provide you the information of what your current defensive and offensive situation.
“ Normal ”: meaning the next rocket will be the normal ones (that does not pierce through)
“ Mega ”: meaning the next rocket will have a larger size and heal you when it hits (Mega Supplement)
“ Pierce ”: meaning the next rocket will pierce through incoming missiles (Silver Bullet)
The left green number indicates how many immunities left, in this example, 3 (Shield Protector)
When you are reloading, there will not be any signs: However, once you finish reloading, the sign will reappear again, indicating the next whatever rocket is ready.
Boss Fight
There will be a huge ballistic missile with 44 lives spawning after any player survives until 444 seconds, and no more normal missiles will spawn afterwards It does not move horizontally, but moves up and down vertically and follows the nearest player.
It also shoots rockets against players, and if the rocket shoot by the boss hits a player, that player will have one life deducted. If a rocket initialized by the boss touches a rocket initialized by a player, both rockets explode and disappear without dealing damage to anyone.
There are a total of 5 levels of boss: Easy, Normal, Hard, Master and Insane. The harder level, the faster the boss chases you, the faster and the more rockets shoot. Note that during Boss Fight, all modifiers will still spawn in a regular interval.
The target of the players is to defeat the ballistic missile together cooperatively by shooting rockets, but at the same time, try to confuse the other player and play tricks on them to make them die faster. If the player touches the ballistic missile, the player dies instantly. Once the ballistic missile is defeated, that means you beat the game! Congratulations!
The red number indicates the lives of the ballistic missiles remaining
Other Game Mechanics
- In addition to an increase of frequency in spawning incoming missiles, the reload speed of rockets will also decrease over time (0. 025 % per second). When the game initially starts, the reload speed is 5 seconds.
- All kinds of rockets take time reload at first. Obtaining modifiers like Mega Supplement and Silver Bullet DOES NOT mean you will instantly have the ammo to shoot the rocket, as the game will still wait for the corresponding reload speed after your previous rocket is shot.
- Please bear in mind that Mega Supplement and Silver Bullet CANNOT be used together. Obtaining another modifier will cancel the previous collected ability as the next rocket will accord the latest modifier when both Mega Supplement and Silver Bullet is obtained but has not been used. For example, if you have collected Silver Bullet previously, but then obtained Mega Supplement afterwards, the next rocket fired will be Mega Supplement. Other than these two, no more two modifiers will interfere each other.
