It's called breach and clear.
You can get it on Ipad and Andrioid and on steam
It's a turnbased game, you choose 4 troopers from Special forces teams.
You have Rangers, SEALs, JTF2, SAS, KSK and Spetznaz.
You have 4 guys to kit out, you can choose uniform, guns, vests, helmets, hats, gassmasks.
Gear is not level based, but guns are, you need a certain number of stars to get some guns, you can kit out the guns, which add to damge, sound, accurcy, range, rate of fire ect.
You then do missions, They are mostly CQC missions, most of the times you have sevral entry places. You can split the team anyway you want. you then plot were each man goes, and were he aims his gun.
The point of the game is to clear the map as fast as possible with out loosing any troopers.
The maps get harder and harder.
I have played on my pad, and now seen sevral types of maps, in the start most are very small CQC maps, I've been to Afganistan, Turkey, South China Sea, Germany and Mexico. The german and Mexico maps are much more open with big open spaces and forests ect.
For the pad versions, you can spend real money to get access to stuff. but you can totaly play and enjoy it with out spending any real money after you bought the game.
Each map has 3 modes.
1 is just kill all bad guys,
2. Bomb defusal
3. Escape.
Each map and each version of it and each dificulty level gives up you to 4 stars. The number of stars decides which levles you have exess to and which guns you can buy.
Very cool and challanging.
And half the fun is kiting out your guys the way you want.
Most guns can fit.
Scope(5 to choose from) Light(3 to choose from) Silencer(2 to choose from) Grip(3 to choose from) Piston(4 to choose from) Trigger(4 to choose from) Laser(4 to choose from)
You can also paint the gun.
And the troopers get xp and level up.
