Grenade launcher and M4 are the way to go. didn't have to worry about using rage mode, or explosives at all. count your M4 shots 1-10 and switch to grenade, hit a crowd, wait for the ding of your helper reload, then pick off the fast ones. an easy, decent game and I don't even like zombie games.
I gets a laggy near the end. I found that the easiest way to fix this was to just let him die and sit there for a bit. I'm not sure what refreshing the page would do to the progress... But it gets to the point where the buttons are sticky or nonresponsive.
I am not sure why there would be AI in a simulation, but this is a very interesting story otherwise. I liked that you didn't give it all in any one branch but did take the time to clarify things with each ending. I read every ending. I kept hoping there would be just one happy ending. I'm sure we're all looking forward to the next one. My one wish is that the story and choices had been incorporated into a playable game. ★★★★☆
So basically, to win all you have to do is get a medic and the rest bruisers and have them all defend a high spot using you as the bait to lure the enemy one by one. To win the capturing ones all you need are bruisers and instead of defending points and trying to stay alive, just go all out and use respawn as your way to quickly get back to the point with full health and clear the area. After equipping my bears with high melee items and using these strategies, it was a little too easy.
Fire + Lightning + Ice = Chaos. No need to upgrade after that. Be sure to kill spirits and fiends to restock on health and magic. I've found that attack + dagger seems to be pretty lethal by being slightly weaker but putting in a lot more hits per second. Although the dark sword of 1000 cuts is even faster. A set of Strong Armor (blue) gives +25 *defend and +200 life. A set of Battle Mage armor (purple) gives +25 *proc and +100 magic damage. Not sure what a set of green, black, or red does yet. Weapon and shield don't seem to effect this any. It's a fun little game. Off the top of my head, the only major thing it's missing is a bit of a plot. That said, I still barely give it ★★★★☆.
Also, after beating the game, the advanced setting can be used to get medals from the same levels and you can even use the same advanced levels to get "6 worlds beaten without deaths". so instead of getting 1-6 and struggling with 7 and 8 you could just do 1-6 and (advanced) 1 and 2 or any combination.
So apparently even bronze and silver medals count toward the total for your impossible badge. The people that have 0 flips on worlds are obvious cheaters. Not sure if this is already posted somewhere, but here's what I've got so far on minimum flips per level. These sometimes require you to kill the llama and respawn. (World 1) 0-0-0-0-0-3-2-1-0-2. (World 2) 0-1-0-0-2-2-0-2-0-0..... (World 3) 2-1-4-4-4-3-4-2-1-6. (World 4) 3-4-2-3-1-0-1-4-0-2. (World 5) 4-5-5-2-1-3-2-0-2-2. (World 6) 4-3-3-2-1-3-0-6-6-4. (World 7) 1-2-1-4-3-2-5-0-2-2. (World 8) 3-2(1?)-2-2-1-1-4-2-1-2(1?). For some reason this helped me get the World 7 powerup trophy that wouldn't unlock before. I just didn't pick up the powerup. Keep practicing in the level until you can get it in that many flips, even if the counter gets high. + this if it helps.
