[TOP1] Royal guards This is by far the best upgrade for your queen, even better if you upgrade cooldown alot with your tasty royal jelly, Why you should get royal guards: -Activates when your queen is at 75% of her health -summons a handful of very strong royal guards to kill anything that is hostile. -very useful in tight situations. - in addition, all your ants spawn for free and instantly for 5 seconds. [TOP 2] Royal Decree This is the 2nd best upgrade to have, but less perks then royal guards. Perks of having royal decree: -Ants hatch for free and instantly for 20s. Thats it. very useful like Royal Guards but not better- [TOP 3] Second wind the top 3rd upgrade is a decent one but not amazing. the perks of having second wind are: -Queen becomes invulnerable for 30s. -Queen regenerates 300 hp over 5s. [TOP 4] Fierce Mother we have arrived at the least interesting and basically useless, here are the perks: -Queen confuses all underground enemies for 10 seconds. Fierce mother is basically useless since, she does not get any bonus to help her (the upgrade basically will only trigger when you have no ants) and she does not become invulnerable for atleast 5s, basically it gives you 10s more until she dies.
