Speaking of challenging, aside from a variety of melee weapons, I thought it would be fun to introduce some new additional effects, starting with Recoil. Represented by a grey icon with a black arrow pointing down, the inverse of the Impact icon, Recoil would affect the Titan using the weapon to attack. Each attack would either push the Titan back opposite the direction of the attack's target, or turn the Titan 45° left or right depending on low-angled (between 0 and 45°) shots.
This naturally had me thinking of the Kzinti Lesson from Larry Niven's Ringworld: "A reaction drive is a weapon, powerful in direct ratio to its efficiency." Which is to say, if you de-couple the cavitation converters on a plasma weapon, you get plasma jets! I would update the card art and label as well, eventually...
