v2.3:

Added a script that teleports all heal beacons to the resurrected medic marine if there are no other medic marines alive.

v2.2:

Flashlights no longer stay activated after being deleted from the marines' inventories as they are no longer supposed to be flashlights.
(Turns out sometimes it still does? Not exactly sure why but I will just leave it at that for now as it has close to zero impact to the gameplay.)

Changed how the script check if it should force restart when no more live Tech marine is left on a Tech-required map, as it was previously too unreliable.

v2.1:

Added a limit to how many sentries can be dropped at one single area.
Previously it was pretty easy to lag the game from the immense amount of sentries dropped at one area due to infinite horde spawns.

v2.0:

Added defibrillators used for bringing fallen marines back from the dead.

Added an one-time use tactical pickup item.

v1.7:

Fixed Mining Laser being single-clipped.

v1.6:

Increased the maximum level of Sentry Damage upgrade from level 9 to level 10.

Added a notification message that displays when a medic is out of meds (this message had to be manually added due to how this challenge's cvars are set).

v1.5:

Added a script that automatically removes emptied single-clip weapons.

Increased the maximum charge Laser Mines can recharge up to from 3 to 4.

Added a command reminding the changes made to the Grenade Sentries and Incendiary Sentries.

v1.4:

Further increased the drop chance of sentries.

v1.3:

Increased the drop chance of all sentries.

Added a command for hinting special pick-ups.
