For a puzzle game, i should be able to finish it on my first try if i think everything through(at least in theory). So, 1 less star rating for invisible monsters
Some people say snipers and javelins are useless. But I think the worst units are the mortar 200 upgrade line. The 300 point upgrade line is better in accuracy, damage, and have a bigger AOE. Snipers and javelins at least have a big range which could be useful in some situations.
Finally beat level 7 on veteran with 0 enemy get through. This level is so hard because there is no AOE towers now, mass infantry is a big problem. The best solution is to kill the APCs before they unload. Recons are the key here. Invest 8 stars to get 2.5x damage for vehicles, put a anti-vehicle recon at each of the 3 frontlines. You may also need speed reloading for both support powers, that's another 10 stars. For the remaining 6 stars, I upgraded rockets up to speed reload, and machineguns to sight. Also, all rockets should go the anti-armor path, since they fire faster and can fire against infantry.
Finally beat mission 8 on hard with 0 enemy pass through. Strategy is similar to gregs', with a small difference. First few waves aren't that hard, the key is not let wave 8 (large wave of vehicles) get through. Save about 900 ref.points by the end of wave 7. At the beginning of wave 8, sell 2 front line mortars each at north,east and west. Quickly refill these 6 positions with level 2 rockets. You may want to give them 200 refi.points upgrade if they get killed, this will make the unit respawn instantly.
A little hit on level 7: get speeds reload for air support and arty support, which cost 10 stars.You should have 8 stars left, I got decrease respawn time for machine guns and anti-tanks, plus speed reload for machine guns. With this setup I won on recruit with 0 enemy got past my defenses.
found a bug. If you use lightning skill 3 to store up lightning balls, once it surpassed 999 it will become 99, so you will lose more than 900 stored charges.(Yeah I managed to store up that many. By the way, lightning skill 5 works fine, though there is still a 999 limit, exceeding charges will be lost as well)
Generally speaking,use lighting for act 1, fire for act 2 and ice for act 3.By act1,2,3 I mean the part before the nth boss. Lighting is good against almost everything in act 1.Fire is good against most undead in act2, only the burning wood are immune to fire, switch to ice and use 1 skill to freeze them,then beat them with lighting. Act 3 use ice for the big guys(dragons, minotaurs and the final boss).
game should autosave after each battle. Got to survival 19 last time, but didn't go to map page, now all the progress is gone, had to start from survival 1 again. Also lost my 30k rubies
lv30 is extremely frustrating. I know what is supposed to do, but it takes exterme precision to get the grenede where you want(probably only 1~2 pixels).
Not sure if this is some kind of cheating or not, playing this on my old laptop with other idle games running makes this game a lot slower, and a lot easier. And i wasn't slowing it on purpose, since i do want the login bouns from the idle game. Estimated fps is 8-12, sometimes even slower
