Star Wars: Commander

“Happens to every guy sometimes this does”
...I found this [GUIDE] Squads

these walls are effective?

but most units simply can walk through them

It's my experience too. It's a way to split up attackers infantry and machines. Most infantry will start shooting at your shields and a Mortar Turret can deal with those troops easy.
I have also tested this on my Empire base, with same results.

I idk if all has these upcoming events, but mine is "Conflict at Anchorhead Pass". It's a good opportunity to get some extra Alloys and Credits if you can advance in League and finance your attacks.
As a bonus there's the Objectives: Sending special troops etc. But I don't focus on these yet.

meanwhile on lvl6 i decided to go for this layout

managed to defend it a few times but also lost a few battles which certainly is no surprise since my defenses are not high lvl yet (most of it is still lvl3... only very few are lvl4 or 5)

the base layout puts every important building behind walls and covered by shields
the HQ has highest protection as its covered by all 3 shields
in each corner of the map is a relative cheap building as a distraction to buy some time (enemy troops might go for that building first before moving to the main base which costs the attacker time if he starts the attack on one of the map corners)

not a single attack in 5 days
is that normal?

i used to get attacked multiple times a day before i did the changes to my base

i hardly can tell if my defense has anything to do with that
actually i focused more on the resource buildings when i hit lvl6
for gods sake these upgrades will be done on friday

They probably moved to Dandoran for the Conflict, which ends in 1 day. Or collecting credits and alloy - there are some "targets" with a lot of resources.
They will probably be back in 3 days, when the conflict starts on Tatooine, for the Conflict prizes.
At last confilct on Tatooine I got the Rebel Vanguard - level 1 (finds enemy traps). An upgrade is available in a Conflict

havent took notice of these events yet

its weird
weeks ago I was able to defend my base... won most of the attacks
I have not changed the base layout.... but upgraded all the buildings to lvl6
now i cant win a single battle anymore

i wanted to upgrade to lvl7 but for meanwhile 2 weeks i cant get the resources together coz everytime i am above 500k metal i get attacked and I loose +100k which is more than i can earn before the next attack happens
during the past weeks i didnt win a single fight

ive meanwhile decided to use my last 100 cystals to buy 24 hour immunity
this way i got to the 750000 metal for the lvl7 upgrade

but actually i still done know what im doing wrong

At that point (HQ upgrade) i spend most of my credits researching. Thinking it was uninteresting to attack - helped a bit.
Later on it helped doing conflict, where reward is paid to HQ and can't be looted.

so its going to get better?

The game gets harder and harder. Vital is that you can collect cash (don't have to win battles) to finance another attack.
Don't mind the level of the opponent (bypass real hard opponents), just adjust the force you use.
Everything gets more expensive, so keep all crystal you collect.

I play this also on my HTC M8 and Pad.
Was playing for over 4 months, major update on phone, re-installed game
lost everything... Meh... can't get it back.. 4 months wasted.

Starting again......

As all games of this ilk, your base defence is paramount.
Try not to attack other players until you are strong enough, also upgrade everything
until you need a HQ upgrade to continue on, thats important as the higher the HQ the
more stronger the opponents will be..
Don't rush it.... the bigger the upgrade, the longer it takes to be completed oc.

Have fun

p.s I am also Cygna on there too..lol

well, ive started the lvl7 base upgrade now
will finish in about a week

most buildings except 2 or 3 are on lvl6, the others certainly will reach that point this week
