Control Walkthrough: How to Beat Tommasi

Tommasi is the first boss in Control, Remedy’s delightfully weird new game that mashes up the extradimensional spookiness of Twin Peaks and the bureaucratic conspiracies of The X-Files in a Metroid-inspired third-person action game. Your first encounter with Tommasi is pretty simple, if you know what you’re doing. Still, it’s easy to unnecessarily die a few times while trying to get the patterns of the boss fight worked out. Let’s simplify that for you and tell you how to take this Hiss-infected creep down.
The battle with Tommasi happens after you’ve claimed the control point in the Communications Department. You should’ve just found a level one clearance card on the body of a dead guard, and you can use it to enter the locked double doors across from that body. As soon as you walk into this large room you’ll see a short cut-scene where Tommasi crawls out of a crack in the wall and then starts to levitate above you.
The first thing you should do is crouch behind something that can protect you. I recommend one of the pillars on the left or right of the room. Tommasi will rip chunks of rock from the ground and walls and hurl them at you, and if he hits you it’ll eat up a lot of your health. There’s a brief moment between when he pulls the rocks up and throws them at you, and he throws the two clusters of rock one at a time. You’ll be able to hear them hit whatever you’re hiding behind, and depending where you’re crouching and how the camera is angled you’ll probably see Tommasi throw them, as well. Once he’s thrown both clusters, you’ll have a brief second to pop out of cover and fire at him with your gun. You can also launch your own object at him; he’ll almost always dodge it, but it gives you an opening to aim and shoot before he can hurl something else at you.
