Once all weapons & armour fully upgraded you can do level 1-8 just by moving ship to centre of screen then leaving it there - the easy way to get all acheivments
Y when i was playing last nite was I able to complete the first 3 waves of "Little Forest" using 1 b asic warrior when now If i don't upgrade him I lose on wave 1!!!
I even have more awards than last nite but my warrior sems weaker/slower than before.
for all those who complain it is a rip off of HoMM, try checking out the heroes of gaia website - They state that the game will be v.familiar to those who have played HoMM, now while you all may not like this game, apart from the lag it is a great MMORPG. just try giving it a chance.
