Tiny Troopers: Global Ops

After some trial and error. It looks like this has to be 25 unique missions. Best way to make this happen is to level up your rank for extra health. Throw in some upgrades on your weapons and you're good to go.

When playing. Beware of land mines. Keep an eye on your troops health. And finally, look out for health packs. If you don't immediately need one. Save it and come back later for it. The levels are short and not that difficult. Good luck.

This cheevo will be awarded for completing 25 different missions without any of your troops going down or being K.I.A

If any troop goes down and requires reviving it will not count for this cheevo and the mission will then need to be replayed.

Don't worry too much about going for this cheevo at 1st.
Spend some time getting to know the mechanics and as you play you will naturally finish a number of missions without losing troopers.

Play on easy

Level up your main character and the troopers make this easy.

On the mission select screen, press x to show the level stats for each level and it will tell you of you've done a level without casualties.

If it says no, replay the level and if you succeed your progression will increase.

Happy cheevo hunting
