Players will be able to find four supply crates on the first floor - to get to the first-floor head to the first stairwell on the fifth floor, rather than ascending the stairs to six, jump down and parachute down the middle of the stairwell to the first floor.

Players will find two supply crates in G-5, the first being found at the bottom of the stairwell where players can climb from the fifth floor to the sixth floor. Open this crate to add an Incendiary MCW assault rifle to the mission arsenal .

To get into the next supply area, players will have to climb the external scaffolding just outside the stuck door and climb inside the window on the seventh floor. Drop to the bottom of this stairwell and open the supply crate to find the Minigun.

The third crate on the first floor is in the middle of the open outside area on the first floor in a doorway on the south side. Players will find the Silenced Expedite shotgun in this crate.

The crate in D-4 on the first floor is hidden at the bottom of another stairwell - players can use the ascender to climb the ascension line nearby or manually make their way to the sixth-floor exterior. From the top of the ascension line turn right and jump down three floors to the window with the yellow tarp hanging over it. Climbing through this window will put players on the eighth floor of the skyscraper, parachute down the middle of the stairwell to find the supply crate that will add the Explosive Crossbow to the mission arsenal.

There are four supply crates available to players on the fifth floor fpsshooter.Com in Highrise.

After climbing to the fifth floor, turn to the right and head to the darkened doorway . There will be a pair of night vision goggle s on the boxes to the left of the doorway, put them on and enter the pitch-black area. Watch for C4 tripwires and claymore mines and push through the dark area to a stairwell that is pitch black and secured with C4. Turn right and head to the end of the hallway to find a supply crate with the Silenced TAQ-M marksman rifle.
