for about 3 or 4 days in a row now I have been getting the "Authentication Failure message - please refresh the page to continue" I've been unable to play at all throughout the days.
I feel like I can't improve any further. I'm on wave 18 but every round I'm using all the money I earned to repair the gate. So i barely make it through the round with like 3-6% gate left then everything goes straight on to repairs. No further opportunity to progress is what it feels like. The games good but this seems over the top.
To have a 90% success rate in killing swordsmen and spearmen. Jump from above and time your sword swing down well. One swipe and they are dead. I literally could clear out like 10 enemies in a matter of seconds by using this method. Avoid using block and strike fighting against these guys, wherever possible. This also works well on archers, but so does block and strike. Also, get an archer to face another enemy as much as possible to get those free friendly-fire shots.
If they have their shields above their head for blocking your incoming strike, kick drop them and then jump on their body to stab and execute them. However, this method usually fails on bosses.
