Sandbags. Very common mobile tactical barrier on other Fallout Online servers (TLA, Requiem,..). Purpose is simple:
1) Block enemy movement (1-5 sandbags on one hex)
2) Block view (5 sandbags on one hex = maximum)
3) Also AC modifier (1-5 sandbags) .. but this is optional, not neccesary.
Very easy to craft, but high weight => you cannot spam locations with sandbags, you need little logistics (brahmin, a lot of players). High weight also gives chance that nobody will steal you your wall immediately, but because of natural Fonline effect (players take, steal, destory, disasemble everything), there is no such a thing as a permanent sandbags spam in cities.
Why i am taling about sandbags again at this moment? Because fonline have entered its midsession and it is time for testing. Players already did all new quests, tested what ever was able to test and a lot of not only PvP players left server. And of course, i really think that adding sandbags and make a few scripts around it is not hard work.
