Tower Survivors: Fortress

Humanity's Last Tower must Turn Into a Fortress
A tower-defense auto battler inspired in the popular Tower Survivors Warcraft 3 mod. 
You are humanity's last standing tower. Enemies pour in from every edge of one fixed screen, and you must strengthen your tower into a fortress to survive. Every 30 seconds eight new potential upgrade cards appear: weapons, upgrades, and synergies. Enemies get stronger as rounds advance, 40 rounds in Standard Survival mode, with many more in Fortress Mode.
Two Modes
Standard is the classic quick game mode: a preparation round, 40 rounds, an elite every ten. No meta progression, no saves, one calculated run.

Fortress is endless and harder from round one. Every death earns Dominion Points for an ever expanding node tree that reshapes the next run: a ninth shop slot, a free reroll every round, a second Hail Mary, an Ankh in your pocket from the start. The standard boss comes at round 40, the fortress boss at 80, and then it only gets worse.

Eight elements, one build
Every weapon carries one or two of eight attributes: Physical, Magic, Fire, Water, Lightning, Nature, Holy and Unholy. Bonuses add up within an element and multiply across them, so a focused build snowballs and a hybrid weapon is the bridge between two builds. Burn, chill, stun, chain, shred and leech belong to no single element, and the upgrades that reward them are where the real combos come from. Orcs, undead, beasts and demons each have a weakness and a resistance, and nothing is ever immune.
