FIRST OF ALL, I AM THE ONLY GAME MASTER, I PUT THE SITUATION, CHARACTERS SOLVE IT
now...
1. Nothing too dirty
2. have fun
3. NO god or overpowered characters
4. Keep OCC in brackets

now, the game flow goes
strike cruiser-------> landing--------> exploring-----> battling the fiend

in the cruiser you can relax and chat a bit until the mission is assigned

Once the mission starts, first goes the landing, in wich a variety of situations may happen, maybe a crash, an attack of ant air tech or a hard landing

Exploring is the main part, you explore the planet's surface and find battles, spoils, and finally, the fiend,

The battle against the fiend is the climax, once it is defeated the group returns to the cruiser, though maybe the ship is attacked or something like that

Once aboard the strike cruiser a new mission is assigned and the process keeps on


now, about the char:

NAME, well, the name
AGE: 18 or older, a bloody futuristic battlefield is no place for kids
EQUIPMENT: whatever armor they wear, keep it futuristic but not overpowered, weapons can be anything, from daggers to laser guns, and accesories, which can be from an Ipod to an anti tank mine
FEARS: what does your char fear? it will be useful when i need to create new obstacles
ABILITIES: maybe you are an extremely fast runner, or a phsyker, or have inhuman accuracy, whatever, just one ability
BACKGROUND AND PERSONALITY: not too big, not too short, and realistic
guess thats it, any doubts contact via OCC
