MvM Upgrades

MvM Upgrades are keyvalue commands sent to the server by the client. To buy a single upgrade you need to send 3 Kv commands.

For example: This will buy a single health regeneration upgrade.

First command:

"MvM_UpgradesBegin"
{
}

Second command:

"MVM_Upgrade"
{
	"Upgrade"
	{
		"itemslot"		"-1"
		"Upgrade"		"60"
		"count"		"1"
	}
}

Third command:

"MvM_UpgradesDone"
{
	"num_upgrades"		"1"
}

This was tested using Sourcemod.

And for refunds:

"MVM_Respec"
{
}
