Player Experience Highlights

Community Insight:

We have been enjoying the challenge BUT 1) To easy to be detected. We spend way to much time moving around or running silent before damaged from destroyers. 2) At 100 meters running silent BEFORE DETECTED has no affect. Always get detected. 3) 100% ducted because damaged should be enabled after certain amount of damage. And options to disable whatever is damaged should should have and option to enable repairs. Its just to hard to evade once detected. We can evade and lose detection without damage – at 100 meters for a short period. But its to easy and quick to get detected again. Seem very one sided. Also, the ability to find warmer water to deflect sonar is missing.

---

When running out of torpedoes, the app give you the option of watching an ad to get more torpedoes. However, after watching the ad, it changes to a highly ornate page which is locked. You cannot play any further and you dont get the torpedoes it has promised. IPad air.

---

Its a fun game however after watching ads you are supposed to increase your number of torpedoes- game locks after watching ads – needs a fix.

---

The game has potential and could be a lot of fun. However, it is not there yet. The manual says the boat is supposed to be invisible under 100, but those destroyers clearly know where we are even if we are at 100 staying still. The second level gets too hard too soon. Put more work in it and it will be a winner, but not yet.

---

It's a good basic sub game. Though, you need to watch adds in order to get perks to survive. Where's the periscope.
