Up.

In the first room at Middle Age 2, jump in front of the table at right-upper corner to the arch where you can find a life.

edit: I found the last hidden room at Conquistadors today! You can see the boat right-upper corner where two sailors with guns appear. You can jump to the boat and find a life and red cubes.

Big tnx.

Btw I always get 94% hidden bonuses in Modern Wars level 1. how to find other 6% bonuses?

Some secrets are not hidden. As the example - the grenade box on the 2nd floor in the stable.
So - grab all items.
There are 17 secret items on this level (5.88% per item) and 4 secret rooms (25% per room).
There are 1 hidden place before the 2nd save (and this secret will be destroyed after you blow up the bunker). And 9 hidden places (with 13 items) after the 2nd save point. So - 3 secrets are "not hidden".

The secret in the 1st floor of the stable - 3 chips. So it adds 17%.

And yes, the secret is the grenade box, not the battery. I have tested.

The 1st secret is in the upper-right corner from the life. The red circle is wrong. Sorry.
The 2nd one - wheels.

3 chips, 17%.

Thanks, I only missed the hidden one right of the destroyed carriage. And to make sure, after the bunker is destroyed you can still have the hidden grenades.

It took nearly 20 years I finally play with 100& hidden rooms and bonuses!

100% of chips in Modern Wars 1? My record is 97%.

Same here. I can't find other 3% chips however I tried and found.
