Hello Commander, and welcome to the Turn-based Tactics Jam 2024, a 1.5  2ish week-long casual game dev competition. 

About

The goal is to make a turn-based tactics game. Something akin to XCOM, Xenonauts, Into the Breach, Hard West, Showgunners, Gears Tactics and similar games.  This means it should include some level of strategic layer as well but it can consist simply of equipping characters with gear or abilities between levels. The games may includes features such as cover, chances to hit, overwatch, as well as strategic layer. But feel free to experiment with the mechanics as long is it is turn based and tactical.

I highly recommend this talk discussing some good rules to follow when developing a turn-based tactics game:
