@TheOneUp: for all bosses except the bird you want to max your DPS. It is basically 5 bullets count, 85-100 lucky strike, and 150-200 Rate of fire (less may be better if you have to sacrify a lot of Damage for it).
For the last boss (7 Final Tech Suits + 1 Night Helmet + 2 Blue Potions) would work better than (6suits+2helmets+2 heal pots) in terms of raw health. Also it is beatable without consumables with 2 helmets which is nice if you want to save funds over multiple tries.
it is definitely a WoT clone, but it would be ok for it's niche (light browser game - why not) unless awful ping. 300ms and all actions waits for the server response - so you may easily find yourself half map away after a lag. And controls.. They just not work as expected. Short 'shift' instantly closes a scope right after open for example.
@Appels, there are no grinding in this game. The classes are cheap, and perk/gear options are not vital. They may make your game easier, may not, and even may render it harder (naked pack, noncombatant). And, to be honest, it is extremely hard to find better flash roguelike.
it would be nice if your soldiers may auto-evade mines. pretty solid game. AI may be better, character classes and skills would add a bit, but it is ok. Can't say it is grindy - only 3 levels require me second try with better gear to make 3 stars, and you always have options to create different viable build. No memory lick, glitches and unexpected behavior.
So.. I don't know where the "Retire" button is, but you definitely shouldn't try to click on "Normal"/"Hardcore" in the main menu after lvl100 - it would simply erase the level progress, and nothing more.
