Talk:SAS Zombie Assault Tower Defense/@comment-32181757-20170602164809

I can only get to wave 75 and I've been playing a while. Some tips:

Cryo grenades not only slow down the Devastators and Ruins, but make them more vulnerable to damage, so it really is prudent to to save these chaps for when the Ruin or swarm os Devastators get close up to your strongest and last positions.

Try to build along the sides of any routes that zombies have to take instead of outright blocking them.

Towards the critical levels, use your meds to make make sure all max upgraded towers/soldiers are ready to take on the tough-as-nails Ruin BEFORE the round starts.

Similarly, use the Nuke at the entrance of the Map for levels you know you struggle to contain.

Dont waste too much time and money on walls and electric wire, in my opinion. Use wire on track corners of high traffic and don't buy more than 5 tank barrier wall sections either.
