I don't know exactly what Mechwarrior Tactics is, but it has a countdown on the webpage that ends on Monday. Two things happen at the end of countdowns: either a thing will be revealed, or a ex-cop will snip the wire on a bomb, saving the orphanage. I'm presuming that it's choice number one, because its from the same people currently making the free-to-play reboot of the original game, MechWarrior Online. You can go to the site and sign-up, ensuring you protect your commander name from the rabble, while I ponder what it could be.
Well, the name "Tactics" is something of a hint towards a more thoughtful, strategic game over MWO's mechabiffs. There is a precedence: MechCommander was a real-time tactics MechWarrior game released towards the end of the '90s. It would make sense to support the action game with a smaller, strategic cousin, that'll reinvest people in the universe while they wait for the main release. I wouldn't expect a straight port, though. They're rebuilding the series and the last peek at MWO made it look like this.
EDIT: Whoops! This trailer has nothing to do with MechWarrior Online. It's footage of a cancelled game. I was taken in, fooled by a group of international Game Writer Confusinators, looking to undermine this site for, ooh, bad reasons. But look at it anyway: it's pretty.
