Achievement LC Engineer

Description
The map for grinding new Engineer achievements. It will be expanded over time with new zones and features.

Main question for me now is if to make second copy of rooms for the Blu team (so totally 32 players may be gaining achievements simultaneously) or to treat Blu as bot team for grinding killing achievements on them (and place spawn points accordingly).

Currently the map has two rooms. Room on the first screenshot has 16 Red sentries in it, which constantly disappear and respawn with period of 8 seconds. There is also a resupply area all over the room. This allows you to grind Silent Pardner achievement - eight seconds is just enough to upgrade sentry to second level. For your convenience you can switch to wrench, type "+attack" into console (without quotes) and leave your beloved Engineer upgrading buildings continuously.

Second room is for grinding both Death Metal and Circle the Wagons achievements. As in previous room, you only have to stand in front of one sentries and type "+attack". If anyone is within fenced area, several sentries will spawn above your head with interval of 10 seconds and immediately break due to laser damage, producing waste metal.

Please give feedback and suggest your ideas for further additions.
