how to increase chance for raider attack?

[Eulivere]

we can increase it?

[Nyc2x]

- as mentioned by Freqsync, Radio towers
- upgrade Vault doors
- send someone to Wasteland

radio tower may help but upgrade vault door and send dweller to wateland can increase chance?

- send dweller to wasteland or quest might be help, your dwellers might meet other survivor or dwellers at wasteland
- upgrade vault doors (I think), because since I upgrade it many raider come to attack or maybe because of the above the reason

Every time you open your vault door, there is a chance of being attacked. Radio Towers increase that chance.

Unfortunatly as you progress into the game a little bit, the attacks become Deathclaw attacks which are far more annoying than fun.

Deathclaws are easy lol they never go past my 1st room ..ferals die in the vault room ...but i need more raider attacks for the 50 raider achivment ...and since im playing on my android save file everything is maxed already ...and i have 17 radio towers and still i get like no raider attacks but 15+ deathclaw/ferals are always on my door knocking xD

How many weapon damages are require at least for deathclaws ?
Is there kind of weapon better than another against deathclaws ?
What kind of room is better to have near vault entrance to stop invasions faster (if you don't let guards at entrance, room based on SPECIAL) ?

If u play on surival mode they will attack more often

i do play on survival and for the weapons i crafted 8 Dragon's Maw(22-29 damage) and all 8 survivors with exo suits ..and all of them are 50+ level with all maxed out stats the room next to the vault doesnt matter i have nuclear plant next to it and radio tower next to it but they never make it to the radio room...they never go past below 75% health during the full raid of the deathclaws...also for stoping raids i have no clues cuz all im doing is to let more come in and not prevent then :/ ...as far as i know having radio rooms and sending dwellers out attract more raids so if u dont want them stop sending them out
