The Simpsons reference:
In the “High Tension” map, go the police station to find a few pink donut
boxes on a folding table in the garage bay. While looking at the boxes,
press [Spot] to shout “donuts spotted!”.
Dead Space reference:
Play the “High Tension” map and go to the second floor of the shopping mall.
One of the stores is named “Ishimura”, which is a reference to the “USG
Ishimura” mining spaceship in Dead Space.
Look for what appears to be a mild-mannered couch in the Dustbowl map on
Hotwire mode. Called the “The American Dream”, players can in fact operate
it like a regular vehicle and it’s one of the fastest to boot. The American
Dream can carry up to four players, and delivers appropriately amusing kill
feed messages should it run over anyone.
In Battlefield Hardline, secret reload animations sometimes display in place
of the standard ones. Your chances of actually seeing a variant are slim:
about 1 in 10,000. Alternate reloads include the pistol spin, the Jedi force
push, the dumb rocket launcher throw, and others. Note that you only see the
animations once you empty your clip, so don’t be afraid to fire those bullets.
The American Dream (Driveable Couch):
In the multiplayer map, Dustbowl, there is a drivable couch known as the
American Dream. You can find a few of them scattered around the map. If you
move your gun over the couch, a button prompt will appear so that you can
enter the American Dream. Up to four people fit on the couch, counting the
driver and 3 shooters. If you run over people with the couch, you will learn
that you killed them with the “MERICA.”
