CANNON CARRIAGE

height - 43.5m
width - 39m
length - 56.5m
total number of weapons - 17

The heart of the Chinese Dragon Train is the engine. It is powerful enough to set all the other carriages in motion. It is crucial that this part stays operational for the whole machine to function properly, therefore it is constantly protected with an energy force field. Nothing goes in or out of this one. If everything else fails, however, the crew can man the onboard defense systems. The one that is immediately noticeable is the electromagnetic cannon, capable of long-range attacks. It seems like it would be the most dangerous weapon on this carriage, but it is the least of your worries.

Each carriage has its own hitbox map. 

The player has the ability to choose which elements they want to destroy.

Joining the fray are multiple cruise missile launchers. They are capable of firing a barrage at the alien core. The projectiles are quite slow, so they can be shot down by the player. Nevertheless, it is a daunting weapon. The carriage also defends itself by shooting at the alien fighter with its quad anti-air guns. Providing covering fire for the engine, their relentless fire is terrifying enough to drive even the most experienced pilots away. Rounding up the arms package are the grenade launchers and napalm cannons, both meant to dispose of anything the X-Morph might have put up on the ground.

The second carriage does not seem quite as dangerous as the first one, but don't let the innocent looks fool you. The massive chassis covers up the satellite dish which the train crew uses to maintain comms with the space station capable of launching nuclear strikes on unsuspecting targets. It is the main weapon this carriage has against the X-Morph, but it comes with a significant drawback. The data transmission is quite long and can be interrupted, giving players a chance to counteract. In addition to calling a nuclear strike, the carriage is equipped with side lasers, capable of targeting the X-Morph core, like in a classic drive-by. Add AA guns to the mix and you have a force to be reckoned with.

The third carriage on the Chinese Dragon Train is a MIRV ballistic missile launching pod. Its main weapon is only capable of long-range attacks, so we chose three points on the map they would be launched from. The train would stop and open up one of the six silos, preparing to launch one of the warheads at the alien core. The whole process is as cinematic as it can be, with smoke, sirens and red lights flashing as the rocket is prepared to start. Apart from adding dramatic flair, it was meant to be a moment for the player to strike, disabling the launch and protecting their assets.

Each weapon system is controlled separately. 
The number of AA guns on this beast was an absolute overkill.

The secondary anti-core weapon is swarm missiles fired from eight side launchers. They compensate their lack of sheer power with the numbers. This attack happens instantaneously, so the X-Morph must shoot down the missiles while they are traveling through the air. Apart from that, the carriage is protected by the usual - flak cannons, grenade launchers and miniguns against the alien fighter.

AIRCRAFT CARRIAGE

height - 31m
width - 43.5m
length - 80m
total weapons - 21

The last part of the train might yet be the craziest of the bunch. Aircraft carriers are some of the most terrifying naval vessels known to man, given their high range and firepower. No water units in X-Morph: Defense meant that if we wanted to have one, we would have to come up with a different idea for that. Therefore, we put an aircraft carrier on rails and made it a part of the Chinese Dragon. To make the whole thing even more obnoxious (in a good way) it serves not only as a launchpad for fighters but also as an aircraft factory! To cut the players some slack, the neverending air assault does not attack the core directly, its sole purpose is to attack the alien fighter.

The aircraft carrier is not defenseless without its birds. 
The plasma cannons on the sides fire relentlessly.

The other weapon the carriage is equipped with is side plasma cannons, shooting balls of plasma at the core that cannot be shot down. The only way to stop them is to interrupt the charging sequence, which might be a bit tricky given the swarms of planes flying around, like bees around the hive. The usual defensive package of AA guns, miniguns, and swarm missiles makes sure that the factory is well protected against all kinds of X-Morph attacks. This rounds up the whole offensive and defensive package of the Chinese Dragon.

The whole package. Notice the purple elements - humans and planes. 

They show the true scale of this monstrosity.

TRAIN TOTALS

highest point - 43m
widest point - 43.5m
total length - 300m
total weapons - 80

In order to take the train down, the player would have to destroy all of the single carriages. Each carriage has its weak spots, such as capacitors, generators, and engines. The player may aim at the weapons in order to reduce their functionality, decrease the damage and increase the charging time. If you decide to go for the weak spots, though, you might be able to snipe the whole part of the train before it becomes a significant problem.

LEVEL DESIGN

One of the limiting factors for designing such a machine is the fact it moves on rails only. It meant that the level would have to be designed specifically to address this need. We decided to place six train tracks on the level. The players cannot see what lies beyond the level boundaries in X-Morph: Defense. That, in turn, gave us a free hand to turn the train back, rotate it, and place it on a completely different track than it previously used. By simply teleporting the boss entity we avoided the necessity of creating a multi-kilometer rail network only to turn around the train of this size. This was supposed to show that the rail network was very complex and required the players to guard 12 points of entry in total.

The layout of the train tracks couldn't be random. Had we simply put intersecting tracks on a flat surface, it wouldn't have made the fight any more fun, just unnecessarily complex. Thus, instead of opting for a flat, desert-like environment, we went for a series of tunnels and overpasses. This element made it to the final game, as it introduces multiple ways the players can shape the enemy paths and take the level on.

Moreover, for a little dramatic flair, the train tracks would not be empty at the start of the level. To evoke the feeling of the humans being surprised by the attack, there would be regular trains all over the map. As with everything in our game, the player could destroy them. However, a more epic assumption was that the player left them alone and the Dragon Train would simply bash its way through all of the ‘regular' trains. It came to rescue humanity after all; you'd better get out of its way!

炮车

高度-43.5米

武器总数-17件

中国龙列车的核心是发动机。它的威力足以使所有其他的马车开动。为了使整台机器正常运转，这一部分保持运转是至关重要的，因此它经常受到能量力场的保护。没有东西进出这个房间。然而，如果其他一切都失败了，机组人员可以控制船上的防御系统。最引人注目的是电磁炮，可以进行远程攻击。看起来这是这辆马车上最危险的武器，但这是你最不担心的。

每节车厢都有自己的接线盒地图。

玩家有能力选择要摧毁的元素。

加入战斗的是多个巡航导弹发射器。他们能够向外星核心发射炮弹。炮弹速度很慢，所以可以被玩家击落。然而，这是一个令人畏惧的武器。这辆马车还用四门防空炮向外星战斗机射击，以此自卫。为引擎提供掩护火力，他们无情的火力足以把最有经验的飞行员赶走。武器装备包括手榴弹发射器和凝固汽油弹加农炮，它们都是用来处理X-Morph可能在地面上放置的任何东西。

第二节车厢看起来不像第一节车厢那么危险，但不要让无辜的人看起来愚弄你。巨大的底盘覆盖了卫星天线，技术人员用它与空间站保持通信，能够对毫无戒心的目标发动核打击。这是该车对抗X变形的主要武器，但它有一个显著的缺点。数据传输相当长，可以中断，给玩家一个反击的机会。除了发动核打击外，这辆车还装备了侧面激光，能够像经典的飞车一样瞄准X变形核心。再加上机关枪，你就有了不可忽视的力量。

弹道导弹发射车。火车的车厢会继续前进

由于火车的体积很大，四倍于四倍的火车轨道。

中国龙号列车上的第三节车厢是一个和平号弹道导弹发射舱。它的主要武器只能进行远程攻击，所以我们在地图上选择了三个发射点。火车将停下来，打开六个筒仓中的一个，准备在外星核心发射一枚弹头。整个过程尽可能的像电影一样精彩，当火箭准备启动时，烟雾、汽笛和红灯闪烁。除了增加戏剧性的天赋，这是一个时刻的球员打击，禁用发射和保护他们的资产。

每个武器系统都是单独控制的。

这个野兽身上的高射炮数量绝对是太多了。

第二种反核心武器是从八面发射架发射的群导弹。他们用数字来弥补他们缺乏绝对权力。这种攻击是瞬间发生的，因此X变形机必须在导弹在空中飞行时将其击落。除此之外，马车还受到通常的保护——高射炮、榴弹发射器和小型火炮，以对付外星战斗机。

带轮子的飞机发射台。多适合活着啊。

火车的最后一段可能是最疯狂的一段。航母是人类已知的最可怕的海军舰艇之一，因为航程和火力都很高。没有水单位在X变形：防御意味着，如果我们想有一个，我们将不得不想出一个不同的想法。因此，我们把一艘航母放在铁轨上，使它成为中国龙的一部分。为了使整件事更令人讨厌（以一种好的方式），它不仅作为战斗机的发射台，而且作为飞机工厂！为了给玩家一点松懈，永不停歇的空袭不直接攻击核心，其唯一目的就是攻击外星战斗机。

没有鸟，航空母舰是无法防御的。

侧面的等离子炮无情地开火。

马车上装备的另一种武器是侧面等离子炮，在核心射出无法击落的等离子球。阻止它们的唯一方法是中断充电顺序，考虑到成群的飞机像蜜蜂一样在蜂巢周围飞来飞去，这可能有点棘手。通常的防空炮、小型火炮和群导弹的防御包确保工厂受到良好的保护，免受各种X变形攻击。整个攻势到此为止！
