Not to be confused with npc_combine_cannon (An unused Episode Two entity).

func_tankmortar is a brush entity available in the following Source Source games or engine branches:
Half-Life 2 Half-Life 2Portal PortalPortal 2 Portal 2Counter-Strike: Global Offensive Counter-Strike: Global Offensive and Black Mesa Black Mesa. This is the Suppression Device on top of the Nexus Building from d3_c17_10a in the chapter "Follow Freeman!" of HL2. The shot will be fired at the exact spot the operator is looking. Note that the operator can potentially be hit by their own shots.


In code, it is represented by theCFuncTankMortarclass, defined in thefunc_tank.cppfile.
Icon-Bug.pngBug:Mortar damage is hardcoded within Source, and as such cannot be changed via entity parameters.
Icon-Bug.pngBug:In Portal 2 Portal 2 mortar controllable by player still work, but don't shoot, also if leave controllable volume viewmodel will invisible and mortar still be under control.
Confirm.pngConfirm: Can be fixed with plugins?
Note.pngNote: In Half-Life: Source Half-Life: Source this entity is very different from other games. On shoot it creates trace line at the end of which forming explosion. Using for some tanks and for guns in c2a5f and c2a5e.
Note.pngNote: ar2explosion use mortar when it shoot, this entity is not in Black Mesa Black Mesa, that means some effects may missed, also console warn about this.
