Obsidian have released a new very detailed video guiding you through various aspects of Alpha Protocol's Safe Houses. Showing off how the Safe Houses work, with all their various character, weapon, etc modifications, it explains how important these locations are. There's your email, which lets you catch up on relationships, find extra work, and keep up with colleagues. There's access to the black market Clearing House, where you can pick up new equipment. You can also customise and upgrade weapons and armour, and all sorts. It's all below.
It's also good to see some clips of the game in slightly less blue-grey washed out locations. You'll also find some glimpses of combat, both ranged and melee. Well, just watch it, now I've told you everything that happens.
And below is part 1 from April, showing how the dynamic conversations work.
