Lancer

Lancer is a gritty tactical combat game on the battlefield and a rules-light narrative game outside of it, so most of the rules focus on the giant robot fights! The core mechanic is rolling a d20, adding or subtracting accuracy or difficulty dice, which are d6s applied when circumstances or your background would help or hinder you, and trying to roll a 10 or better. Accuracy and difficulty dice cancel each other out, one-to-one. The game master might also decide that a roll is risky, meaning there are consequences even on a success if a character rolls less than 20, or heroic, meaning the character will only succeed on a roll of 20 or better. Player characters also have access to triggers, broad abilities that allow them to add bonuses to rolls where they apply.

In combat on each player's turn, they can move and either take a "full" action , like a barrage of weapons or stabilizing and repairing, or two "quick" actions, like fast attacks, grapples, and bursts of speed. They can also overcharge, taking an additional quick action at the cost of heat, a limited resource that tracks how close your mech is to overheating and potentially exploding. Mechs also have stress, which helps mitigate overheating, hit points, to mitigate structural damage, and structure, how much structural damage they can take. Every time you run out of hit points, they recharge, but your mech will take some structural damage and risks being destroyed.

Characters in Lancer can customize their mechs, which means each mech frame will have unique access to weapons and abilities that expand or alter their options in combat. They can also scan enemy mechs to learn their capabilities, as well as engage in hacking and electronic warfare in addition to standard combat. Outside of the mech, characters can repair and upgrade their frame between missions, as well as blow off steam in downtime and bond with their fellow pilots.
