I just got this game yesterday and i am stuck on only the 3rd level, please help me!!!
This game is soo hard!, but good!

What part are you stuck on? Be more specific and I'll try to help

oh yeah, im up to the very end part and you have like 4 smoke grenades..

Sometimes it's best to keep all the guys together in one defence rather than spread out between the 4, then they can heal eachother if one goes down, send your guy with the grenades out when it's clear, lob a grenade and get back in, it's probably better to check out the map first so you dont take too much time in the open

I managed to get most of the guard spawns from behind the sandbags, just check out the map and use the compass to line up with the spawn, then chuck it over using the right stick to throw higher if you need.

Since the grenades keep spawning you can miss a few times .

yeah, cool thanx ill go play it now.....
