Maybe it's just me, but the map looks messy as hell. Four players, six lanes, and unless there's a pre-set plan going on, everybody's either:
1) Mass building towers everywhere
2) Focused on their own 'lane' and not helping out.
Met a couple of guys on the leaderboard one game. Didn't know. End up flaming the hell outta me and the new guy. Asked for towers like Blacksmith 3, didn't want to build. /rant/
With 6 lanes, bounty is at 1.5x of a normal game, minus the last five waves. Don't know how much that is so I cant give an exact multiplier.
I really don't like the co-op version for pubs, but for playtesting sake, I'm gonna find three other people willing to try a strat out. Probably seems like the best if you wanna climb the leaderboards. As for 'for fun', it's so messy I can barely enjoy it. Better sticking to the solo map if playing alone.
People seem to favor long-ranged towers (coughlightcough) such as electricity and gunpowder. Played about 5 games, and those who, I could see, knew how to play the game, ended up only with these towers. Me, meanwhile, while trying to break the trend, played with Quake and the likes. The result? I can barely hold one lane while they're just tearing two lanes apart with ease.
As usual, people still tried life towers, and I can say it's pretty effective you aren't trying to climb for leaderboards. Especially good with new players playing who don't know how to play.
Early (1- 15)
Very confusing. didn't know where to build. A lvl 1 dual-element is brain-numbingly easy, allowing you to last about 5- 10 stages. Didn't try arrow and cannon towers, but I'm pretty sure other then for leaks, they're pretty much obsolete in coop because of the increased cash.
Game spikes pretty hard for new players, who often mass their towers, get random elements and build random towers. As for the experienced players, the hard decision is whether to help a struggling side or build more on yours for that one rainy-day wave (nothing more sad than bulky dark casually walking through a vapor tower). At this point, the difficulty almost equals to v.hard on the solo map because of the lack of gold and increased creep count / creep bulk.
Nearing the end (31-40)
Most people just die, ON normal. And it's not because we used to camp our spawn so that the poor life tower builds can't handle the rush. New players never make it past here, and those who do, do build towers like gunpowder, light etc. In the current game, there really is no space for short-ranged towers.
Only been through it once. Difficulty goes back down again because by now, you know what you're doing, and whatever you are doing /works/. You just kinda upgrade the T2 duals into T3 duals, build more T2 tri-elements, and save for Pure Element Towers.
UNLEASH THE FROGS
Not much of a comment. Usually last about 2 - 4 rounds unless interest was accumulated. Nothing really different from solo.
In short, only play this with a pre-made team. Playing pub is pure suicide.
