Intel HD 4000 is not an actual video card, it's part of the i7 CPU that is dedicated to video. It won't run very well. You would have to play on lowest settings, plus a low resolution probably below 720p.
You could add a video card, as long as the PSU has enough power to run the video card. You might have to upgrade the PSU depending on how good of a video card you want to buy. If it's a laptop it's more tricky to add a video card.
