i wanted to find an old classic game i used to play all the time. its in the style of kingdom rush, but its not a tower defence, you had 5 or 6 heroes: assasin guy who attacks fast but is weak, normal guy with sword (average), axe guy slow attack speed but high dmg and i think later on more classes get unlocked. you had abilities with cooldowns and you made a party of 3 or 4 was it heroes and you can play 1 or 2 at once (wasd and arrows (with friend i suppose)) and the others were ai. there were levels and leveling systems for your heroes and i loved it.
