Surpisingly good.
I bought XCom Chimera, Gears Tactics and Troubleshooters in the same week, thinking that the latter would end up on my pile of games to play sometime in the future...
Steam says I've played 6 hours of XCom, Gears Tactics I've played around 1-2 hours (thanks to gamepass). Troubleshooters... 39 hours.
I agree.
This is the quality of translation you're getting if you buy the game now. Devs have commented on the forums saying they will improve it.
The translation didn't bother me so far. OK some explanations are weird, but to me it's tolerable.
I like the story, it makes me want to learn more about the world and the characters - I find Gears Tactics' story worse / generic in comparison.
The game is a bit too easy on normal if you aren't new to the genre, but on the other hand, the game throws you into larger fights with several independent groups of player controlled characters rather quickly.
