We saw a mission where Michael Thorton, the main character, had to infiltrate a yacht, find a key player from an enemy faction, and extract key information. The choice starts with how you approach each mission, and Obsidian decided on stealth. Apparently, Alpha Protocol can be played from beginning to end without ever firing a shot, and sure enough, we saw a procession of lethal and non-lethal takedown moves that never once gave away Thorton's position.
Your ability to stay hidden can be strengthened by developing your character's perks and abilities. In this case, the screen was marked by coloured arrows that indicated the positions of all the enemies in the vicinity and which way they were facing. Another skill allowed Thorton to become invisible for a short period of time, and suggested that Alpha Protocol will indulge in some flights of fancy to alleviate the gritty realism. Indeed, a brief skirmish with Sis – the enemy faction's key female operative – at the end of the mission seemed like it belonged in a run-’n’-gun shooter rather than a forward-thinking RPG. However, once Sis had been pacified Alpha Protocol retruned to its key strengths: character interactions and moment-to-moment decision making.
