There's a
preview on Eurogamer.net and an
interview on RockPaperShotgun.com, both of which were somewhat informative. Though, the former is rather an account of what playing the demo felt like, while there's more information in the interview.
Several parts I especially liked, mostly revealing how this is apparently still a proper X-Com game:
We’re forging a new mythology, but what we’re retaining is the core elements that made X-COM X-COM; the strategy, the base, the research, agents, all of those things being in charge, and dealing with this problem as you see fit.
There is a sort of dynamic level element. [...] The game is generally fairly unscripted. You’ll not be able to expect where these enemies are coming from or what you’ll encounter on any given scenario.
[...] You can leave a mission at any time, but the longer you stay, the more stuff you can obtain like research and other findings, but the stakes are also increasing so you’re faced with this filling one bucket with stuff and emptying the other bucket of health and ammo and everything else and the foes are getting stronger and eventually you have to evacuate.
Thanks to the evidence you collected on prior missions, your scientists have been able to research the Blobs and then come up with a counter-measure. With the blueprints passed to your engineers, you can now order up as many flame grenades as you need - and they scorch a Blob into so much flat tar in seconds. Use 'em sparingly, mind. You can only take so many with you on each mission, and they cost a ton to manufacture. Money doesn't grow on trees; money grows from government funding, and that's something you need to earn.
Keep moving, keeping fighting - all the while keeping an eye on your worryingly diminished reserves of ammunition. Once it's gone, it's gone, and you'll have no choice but to run. Don't go thinking you'll find a box of ammo lying helpfully in the street. This is the real world, sunshine.
XCOM isn't a strategy game, but it is a game about strategy. It's about preparing for a fight, dealing with a fight and then knowing when to cut your losses.
