Metal Sword is a tight, compact, Forged In The Dark game where you're a squad of mech pilots.
It feels *a lot* like Front Mission.
The PDF is 3 pages, but it's packed full, and the level of content that's been somehow squeezed in reminds me of Succulent Sorcerers.
That said, the PDF does start on the third page, and then you read upwards, so it's sort of a weird first impression.
Mechanically, the Blades engine isn't explained in huge detail here, so you may want to read the SRD or be familiar with Blades first. If you are familiar with Blades though, Metal Sword does a great job of hacking the engine to focus in on the elements that work best for a squad-based mech game. For example, your character and their mech are made up of quirks, which are functionally small two-hit pieces of your overall hp. Break quirks, and they come back changed. This is maybe the best way I've seen a game do "limbs have their own hitpoints", and it feels cool instead of cumbersome.
Other gameplay elements all fit pretty close to the Blades style, and gameplay is objective-oriented and squad-focused. The dice might be a bit swingy, and it's on the GM to decide when the group's been through enough and a given mission is over, but these are both issues in Blades as well, and can be handled through good use of clocks.
Overall, if you like crunchy mech games but don't want an extremely granular ruleset, this delivers. And if you're familiar with any Forged In The Dark game, Metal Blade will be very easy to learn. I would strongly recommend checking it out for short campaigns in your real-robot setting of choice.
-Does each PC do one of each Downtime Action in every downtime? The text implied this, but I couldn't tell for sure.
-Does pushing yourself using a quirk cause that quirk to take two damage? The text seems to imply this, but likewise I couldn't tell.
