One popular theme is the relationship between soldiers in XCOM 2. Writers often explore the deep bonds that can form during combat and how those can turn into love. For example, a story might focus on two soldiers who start off as comrades but gradually fall in love as they face the challenges of fighting the aliens together.
Another theme is the love between a human character and an alien (in a more sympathetic or unique alien form). This can add an interesting twist as it involves different species and cultures. It might explore how they overcome the differences and prejudices to be together. For instance, a story could be about an XCOM agent who falls in love with an alien who has defected from the enemy side.
One popular trope is the relationship between a soldier and their commander. It adds an element of forbidden love or a power dynamic. For example, a rookie falling in love with the battle - hardened commander.
One popular xcom crossover fanfiction is the one where XCOM agents cross over with the Mass Effect universe. It's really interesting to see how the XCOM combat strategies are applied in the fight against the Reapers. Another great one is the crossover with the Warhammer 40K universe. The grimdark setting of 40K and the high - tech nature of XCOM create a really unique blend.
One common theme is the exploration of the Vipers' nature. Are they just mindless enemies or do they have more complex personalities? Another theme is the conflict between XCOM and the Vipers. It's often about the battles, strategies, and the struggle for survival. Also, there are themes of redemption and transformation, like a Viper changing sides or XCOM trying to understand the Vipers better.
I'm not entirely sure which specific 'xcom lemon fanfics' are popular. Fanfics can vary greatly in popularity depending on different fan communities. You could try looking on fanfiction websites like Archive of Our Own and search for 'xcom' to find some, but be aware that 'lemon' often implies mature or adult - themed content which might not be suitable for all audiences.
Some great xcom fanfic stories include 'XCOM: Shadows of the Past'. This one might explore the backstories of some of the main characters in the XCOM universe. There's also 'XCOM: Future Horizons' which takes the story into a more futuristic setting with new threats and challenges. Additionally, 'XCOM: The Underground' could be a cool fanfic that focuses on a secret underground movement within the XCOM world.
One great XCOM Viper love fanfic could be one where a soldier overcomes the initial fear of the Viper's menacing appearance and discovers a misunderstood side of it. They start to communicate in a unique way, perhaps through shared experiences in battle.
In such fanfics, the theme of sacrifice often appears. The Viper or the human may be required to sacrifice something important, like their standing in their respective communities, for the sake of their love. Another theme is the exploration of identity. The Viper might start to feel more human - like in its emotions, and the human might question what it means to be human when in love with an alien. And mutual understanding is also a big theme. They have to work hard to understand each other's instincts, motives, and behaviors.
Another theme is loyalty. The loyalty of the soldiers to XCOM, and sometimes the complex loyalties within the XCOM organization itself. For instance, when faced with the allure of the Chosen's offers, some characters may struggle with where their true loyalties lie.
One interesting Xcom fanfiction could be about the soldiers' personal lives off - the - battlefield. For example, how they deal with post - combat stress and form relationships within the base. Another might be a story that reimagines the Xcom project from the perspective of an alien who has been captured and is trying to understand the humans' motives. There could also be a fanfiction where a new recruit has some sort of special power or ability that changes the dynamics of the Xcom team's missions.
Many XCOM 2 fanfictions explore alternate endings or scenarios. They might imagine what would happen if certain key battles were lost or if new alliances were formed. This gives readers a chance to see different possibilities within the XCOM 2 universe.
