LOL. i win on most actions! 16k YES. i got really bored... it was random map, i wouldnt have chosen that for survival

But on more serious note: here are my suggestions for bonus goals:
1) First one to build the first tower. (might be unfair though, since player positions change, but still, i think it would be fun: everyone trying to be the first, and then you see who won that achievement ).
2) First one to kill all of the creeps of that round. (this can be won continuously).
3) First one to upgrade a tower of 3k cost.
4) First one to build ultimatetower.
5) First one to upgrade ultimatetower.
6) Last one to lose first life. (you would get this also if everyone loses life except you).
7) Player whose creeps go the least distance each round. (this can be won continuously).
8) First one to fill the whole map with towers.
9) First one to fill the whole map with fully upgraded towers.

... more?

1) First one to build the first tower. (might be unfair though, since player positions change, but still, i think it would be fun: everyone trying to be the first, and then you see who won that achievement ).

If you use shortcuts every body will build the first tower at the same time.

I think goals like this are unimportant.
In 1.0 this mode will be more interesting.
