Well, for a Mech-lover like myself, today's just a red-letter day, what with two mech-based games to talk about. This one comes to us from Two Hour Wargames and is called 5150 No Quarter. This one's pretty straight-forward. Just grab whatever mechs you want to use, however many you and your opponent want to use, and get ready to throw down.
The game has rules for being played solo, teams, or head-to-head play. there's both a single-battle and campaign mode. Control from 1 to 24 mechs at a time. There aren't any specific models for the system, so use whatever your favorite mech models are. The game is compatible with other 5150 titles.
