Way to survive Endurance mode
1. you are going to need a good bot that reproduces fast, shoots fast, has good health, and good damage, so go after the spider factory FIRST
2. There are alot of storms, so build pyramids so your robos can survive both the waves and the lightning (build 2 pyramids)
3. Max out reproduction rate for all the current buildings, then speed, then fire rate, then range.
4.Use the lightning to your advantage, build a lightning tower.
5. Whenever you build a new tower make sure you max out reproduction rate, speed, fire rate, strength and range first.
6. Now make a radio station for an increase in defense, if any robots get pass your waves, the snipers will take them out easily.
7. Make a Hospital to ressurect dead robots.
8.Build a mage tower, to heal survivng robots.
9. Build a tank factory
10. Start building buildings of w/e you like, as long as you make sure that you are able to summon robots fast, because they will keep using the EMP.
Now enjoy and watch as you shred the game!
