We played XCOM 2 and we thought it was brutally hard, just like it’s predecessor. You can read about that here. Also revealed XCOM 2 will feature three post-launch content drops part of their Reinforcement Pack.
Here’s the content detailed for the Reinforcement Pack:
Anarchy’s Children: Rebellion-themed content with more dramatic soldier customizations. Available Spring 2016.
Alien Hunters: New gameplay highlighting an elite alien hunting unit of XCOM as it tracks down “Ruler” aliens, plus a new mission, additional soldier customization options and more powerful weapons and armor. Available Summer 2016.
Shen’s Last Gift: Introduces a brand-new soldier class with unique upgradeable weapons, armor and customization features, as well as an additional narrative-driven mission and map. Available Summer 2016.
The Reinforcement Pack will be a part of the XCOM 2 Digital Deluxe Edition which also includes the soundtrack for the game. You can also purchase the Reinforcement Pack separately if you choose to buy it post-release.
