The map is relatively small compared to other maps and plays host to intense and fast paced matches. There are many blind corners, narrow corridors, and dark areas, all of which encourage players to camp. It also provides fast paced Free-For-All and team games. Conversely, there are large open spaces and high rooftops which allow players to snipe. Airborne Killstreak Rewards such as the Harrier Strikes or Attack Helicopters have limited effect due to the high availability of cover. Conversely, UAVs can help root out the players that are taking cover. The thin walls allow players using Deep Impact or FMJ to kill people window camping, or those defending bombs in Search and Destroy or Demolition.
In Call of Duty 4: Modern Warfare there is another version of this map called Winter Crash. It is similar to Crash, but with a Christmas theme. It is only available on PC and Mac. It then became remastered and was included in the Call of Duty: Modern Warfare Remastered December Update, this time releasing for all platforms.
Near the USMC/TF141 spawn, off-map to the right of the grassy hill, there is a signature written clearly in sand bricks. This is easily visible in free-spectate mode. The signature reads "REMY".
In Call of Duty: Modern Warfare 2 the destroyed cars have been replaced with functional ones that can be destroyed. Players can crawl underneath the white pickup trucks before and after they have been destroyed.
In the top floor of the building behind the crashed helicopter the player can see a photo on the wall, showing two people on camels, dressed in Arab attire. These are actually employees from Infinity Ward, during their research trip in Egypt for Call of Duty 2. The man in the front is Grant Collier, former president of Infinity Ward.
When on the top level of the three story building, grenades from grenade launchers can not go through the fencing.
