The D20 game system has a multitude of feats across several different games. Far too many to be sifted through and sorted out for this homebrew version of Warhammer 40K to the D20 system.
That being said, if a player wishes a feat to be added to the game, or his character, they will need to present them to the Ops of the channel for review.
The Feats will have to fit into the setting, and the feel of the game. Feats that introduce new mechanics will be denied, however the Ops will look through the mechanics changes to see if they can be adopted into the game itself. For now, the mechanics of this game are the base settings for the D20 gaming system, alterations and tweaks that come from various other games are subject to review.
Most D20 games hold a varied list of core Feats, feats that augment skills or provide new abilities. Most core feats are available to this game, seeing that it blends a Midevil and future fantasy feel. Below there are links that can point players in the right direction for picking feats.
