US Colonial Marines uses the Aliens Adventure Game rules from Leading Edge games. The combat system is unlike most pen and paper role playing as it do not have hit points in the traditional meaning. Instead it is a very realistic system using tables.
Combat in the Aliens Adventure game is notoriously deadly. You can, and will, die from a single gunshot wound routinely. To sum things up. Don't get shot, ever. To avoid this it is recommended to always have Your character in cover. Only move while someone else is supressing enemies and avoid frontal assaults at all costs.
I cannot emphasize this enough - Because I don't fudge die and will kill Your character if dice and tables says so. I have run a few mock combats with the system and it is nasty. Really nasty. Way more so than the previous systems we have used in Aliens. If You get a solid hit from a Pulse Rifle You either die or are disabled for the rest of the fight.
This do however spice up the game and You have to be both smart and lucky to survive. Luckily it is very easy to create a new character with the new system...
Game on.
