Monthly items
Every new month there will be different items in certain rooms in the raider base. The rooms you look into are the ones on floor 1. The debris blocking the two rooms can be cleared by talking to the raider there and when he asks for a donation give him 100 ec or 300 ec (Just to be sure I gave him 300 ec but you could try 100 ec) and leave (what I did was use the transever to transport from oil field area 3 to oil field area 3) and when you come back there will still be debris but there is a room exposed and in the room will be several boxes just destroy them and they will ALWAYS give you a health item, a BM item or some ec (they will not drop BM upgrades, life-ups or subtanks) and in one of the boxes will be a random health healing item or something like that (like a lollipop which heals 5 health). To get into the second room you must first defeat the final boss, Albert, and then return and go to the level 1 in the oil field area 3 and talk to the raider and he will ask for a donation of 100 ec or 300 ec so give it to him and leave and come back and the second room will be exposed and there is only two large boxes in the second room which only drop the big form of ec and the biggest health item. But they might drop a useable chip (like the ones you get in item section B). These are cool things that would be pretty cool to have. You only get each chip once and the Room A items will only appear once per day. Hope this helps everyone!
