Mobile Strike Walls
© Epic War LLC

In Mobile Strike your walls provide additional protection against attacks, by housing traps that can kill attacking troops.

Upgrading your walls increases their capacity, allowing you to store more traps. Once your walls are at level 21 you will be able to store 125,000 traps and will also receive a bonus to trap attack of 10%.

When your base is attacked, your traps are added to your defending troops when calculating whether the attacker or defender wins. Having more higher level traps can significantly tip the odds in your favor, killing more of the attackers troops and resulting in less losses for the defender.

You should also spend some time researching trap attack and defense boosts at the research facility, to improve your traps further. New traps can also be unlocked through research.

You are required to level up your walls to the same level as your Headquarters, before you upgrade your HQ. Walls take a huge amount of stone to upgrade in the later levels, more than any other building in Mobile Strike.

The table below has the build cost for each upgrade level from 1 to 21, the build time (before boosts), buildings required and the power rewarded.

  1. I’m having a hard time with traps. Sandbagging works fine, but trying to build anything second tier like barb wire or tank traps is impossible. Spent hours in research unlocking these things, but when I go to my wall they light up and open fine, but the build button is always grey. Tried building my resources and commander – nothing helps. Wasn’t bad early on, but I’m almost to level 10 and most of my time is spent trying to figure out how to defend the darn thing. I’m getting tired of buying 8 hour shields and hiding until they go away. Once these traps are activated what’s the trick in actually getting them to build?

    • As soon as you unlock a trap you should be able to build it in your walls (assuming you have the resources). However, traps take a long time to build and can be destroyed very quickly. You are better off concentrating on training troops and researching abilities to improve your troops in the early game.

      • Hey, thanks for responding. So, I guess it’s not me – it’s a glitch.

        There lies the problem. The game is based around the help wizard guiding me through an orderly required build sequence, not only to guide for smoother growth, but to give me required gifts. Without direction I’m at a disadvantage as I go up. Defense is half the game. It’s like walking with a cast on your leg – yeah, you can get the job done, but you won’t win any races. Not a good place to be in a competitive game. Besides, the thought of the pop ups and hand on the screen urging me to buy trip wires forever would drive me nuts.

        I first noticed when I was at level 7. I attacked a 7 who was using trip wire and tank trap D and thought, “Hey that’s cool, he stopped me dead, wish mine worked, oh well”, and just kept playing, Today after building my Level 10 HQ I need it for the game to work past just being novel. I’d like trip wires and tank traps, sandbags count as kills.

        Just sent off my third email, sent the first at 7, to the people for direction. This is no longer a minor glitch that can be ignored. Do you have a contact with these guys? Do they have a customer service? I guess i can just hobble on until they respond or find something else to do if they don’t. I should probably give it more than a week – I have time and money invested at this point.

        Thanks for getting back to me. Man, I hope I don’t have to start over.

        • If you e-mail me a screenshot of your trap research tree and a screenshot of your walls to mobilestrikedata@gmail.com, I’ll see if I can figure it out.

          • Thanks for the offer – figured it out. I just knew it was going to be something so simple it would be stupid simple. What I failed to realize was all the second tier and beyond traps have to share the capacity of the sandbags – you can’t just max out sandbags and then add to it. My usual strategy on huge time drain items is to just go max and let it build when I’m not playing. I never like to use speedups on things that can be lost. I decided to drop the trap level…what do you know, I can build barb wire now.

            Thanks for your help – it really got me thinking.

            I know the strategy of traps and quick shields work, but it can be zero sum. This last anything goes challenge my little level 8 with full sand trap and 4k troops withstood the initial blast of 46,000 – took out all my traps and half my resources, but none of my guys – while he lost 300+. On paper this was a loss, but this challenge only troop death counted. He hit me once and I put up an 8 hour. Earned a bronze for the alliance, just out of dumb luck.

            Again, thanks – this is a cool site.

  2. Question. Do the walls themselves provide protection, or is it just the traps. Not sure if the walls protect and allow traps to help or if the walls just provide space for the traps.

    Not really explained anywhere.
