XCOM 2 is a PC turn-based strategy game where you lead a resistance force against an alien occupation, managing resources, researching alien tech, and commanding soldiers in tactical battles. For PC players who’ve beaten the game on hard difficulty, what’s the most important strategy for keeping your soldiers alive in battle—do you focus on cover (to avoid enemy fire), overwatch (to ambush enemies), or using special abilities (like grenades or healing)? Additionally, soldiers can be customized with different classes (e.g., Ranger, Specialist, Sharpshooter) and perks—what’s your favorite class combination for a balanced squad, and how do you use their abilities together to take down tough alien enemies (like Sectoids or Mutons)? Finally, XCOM 2’s PC version has a War of the Chosen DLC that adds new enemies, allies, and mechanics—do you think the DLC makes the game harder or more enjoyable, and did it fix any of the base game’s flaws (like repetitive missions)?
