What’s unique about this version is the live upgrades. Where other versions only allow you to upgrade when you die, this let’s you upgrade while fighting. You can make attack upgrades, defense upgrades, and even money upgrades. As a strategy, try to prioritize upgrading your gold bonus first so you can earn more coins. Once you have enough coins, you can fortify your castle health and defense strategies. The game goes on and on. It’s great that it saves on your browser. You can pause and pick up where you left, any time.

Your enemies arrive in waves. With each wave, your enemies become stronger and arrive in greater number. Without prodigious upgrades, you will not last long after the first few waves. Another key difference with the previous Hold Position games is in game time. There’s no defined end-goal of surviving for ten minutes. You keep playing until your castle can withstand no more. These major changes doesn’t detract from the series’ main appeal. You don’t need to farm anymore, though.
