Weapons don't disappear from your inventory, you have 4 weapon slots and when you replace them the original one is gone (i.e. you have a pistol, you take an axe, you lose the pistol and keep axe). So be careful.
Awesome game, and the fact that the developer took the effort to fix bugs is simply amazing. Nobody seems to do that.
Can ANYTHING be done to reduce the lag? I have set everything to the lowest possible setting and still the lag is unbearable (tank gets stuck moving in a certain direction for about 5-7 seconds after I stop pressing the corresponding key, leading to me getting pwned). As soon as there's a lot of opponents/bullets in the arena it becomes impossible to play.
Extremely buggy. Keeps getting stuck, e.g. enemy engineer goes for a stranded structure, destroys it and keeps walking in place and I have to restart the level. Get rid of the frequent bugs and it'll be a great game.
There is really very little point to adding commands like "retreat" or even the option where you click where you want the hero/troops to go if they almost never obey the commands, isn't there? This was a huge issue with EW3 (any semblance of control was non-existent), I see it has not been resolved. Pity.
In the power-up stage before the last level the keys stop working and the lag is horrible??? It was working absolutely fine until that level, but that one's completely unplayable.
Gas planes malfunction often - they do not leave a trail, just a cloud underneath them that kills them off. I don't know if this is a bug or was done to make the game more realistic (gas deployment malfunctioning - not a bad idea), but it's annoying as hell.
Saves are still getting lost, and saving to Kongregate is just not working. Creating a functional "Save" option is really not that hard, there are several games here that allow saving. Absolutely idiotic. Not that bad a game, though, so 2/5.
