In Nicemetal, you have to use your turrets to stop a giant mech from breaching your base. As is par for the course, the mech follows a predetermined path. Curiously, the position of your turrets is also preset.
Unfortunately, none of your turrets are manned. What you have to do is click on a turret to send one of your troops to it. You have a limited number of troops and they also seem to get bored or perhaps just tired and will only man a turret for a short period of time before heading back to base.
The key is to keep the right turrets fully operational for as long as possible. And watch out for the mech squishing your troops as they rush to and from the base.
Oh, and since it's Japanese, you won't understand the menu. Just keep clicking skip and selecting each option until you see "Stage 1" on the menu. Click that and the game proper will commence.
Thoroughly recommended. I'd like something like this on iPhone, if anyone has a suggestion?
