Actually I find the homing cluster to be the best weapon for speed or normal rounds, tears bosses up fast, got speed gold on every one first try no need for a nuke.
Road Track hard... crashed twice on me past level 100.. the last I was on 109 but the high scores still only say 102.. its BS. I have a VERY high end comp too, shouldnt be crashing.
your first time play on casual and use the cheats.. once you have some badges itll get easier. No need for range penalties and the mobs move slower, etc.
for new people having problems, some say bowgun is best, I say get a rogue and use a revolver, NO other pistol. HOLD down the spacebar and it will reload after EVERY shot, it reloads faster then you can shoot. Its great damage too, mow crap down. It you cant get a revolver before level 10 it will get very hard very fast, possibly restart.
the new classes are not that great, just different. The objective is to play it several times getting further each so when you restart you have more bonuses, which obviously make it easier to get further.
reload is spacebar, and for a weapon that doesnt use a magazine you can load 1 shell at a time, hint hold down spacebar as you shoot youll reload after every shot.
the targeting priority is the first to appear on the screen, so they often shoot at a slow one thats been on the map for a while and ignore a fast one that rushes past it. you have to plan for it...
yes you can shoot faster then 1, it just doesnt display... you can get to at least .5 I know cause Ive been at 1 reload and it went a LOT faster with another speed boost
And for the guy having probs with 21, the middle is king obviously. I put 3 squirts and 1 dart in there. block the paths so the left right goes right through the middle but ALL you attacks are hitting them. Have the upper come around to that left entrance and they follow that same path; so they go in a zigzag. I also put a swarm tower North of the center but touching the 2 level 5 boosts so they all go south of the middle and that swarm gets boosted.
If your having trouble with 13 use nothing but pellet towers they are very cheap to upgrade and just a few to lvl 3 will kill everything. Connect the 2 entrances by a simple maze, and your target is as many level 3 pellets as you can get. Level 4 doest hurt but even for the bosses 3 is enough.
The havoc fires automatically, its a short range point defense laser type.
I have to agree with several others here, too short, It was good enough I would have loved to play it longer. Only down side I can see is you need multiple ways to perfect your ship, different types of weapons so you can choose a couple different ways to be 'fully upgraded'.
buggy with lag, and waaay too much time and lives in the later levels, immpossible to lose if you have a clue... quite aroudn lvl 90 didnt wanna keep going for another 6 hours
