Two rewards tutorials in one day?!
Tower of Guns this time.
Why would you do such a thing?
£0.10
Easy, just jump on hugbots Mario style in the first room. You can soften them up with a gun if it's sorta hard jumping on them. Someone reported having some issues with the achievement popping up, but it worked fine for others, so YMMV I guess.
And You Thought Magnetized Loot Was A Good Thing...
£0.25
There's a hard way to do this (the way I did it) and an easy way to do this. Hard way is going through a level normally, making sure not to pick up ANY drop the entire time. This is tough, since there are coins all over the place, cards to level up your gun, health drops, etc, not to mention the very first room has a row of coins that you can only avoid by triple jumping over just right. Louiedog, however, informed me of an easier way, in which you die 4 times or so, then the game will spawn you in a different level that's extremely short, has no enemies, and allows you to skip all the drops. That makes it really easy, but I don't know how often you come across this special level, so make sure to do it right when you have the chance.
Yes, Bombots Self-Destructing Counts...
£0.50
The name of this achievement tells you exactly why it's a pain in the ass to get. You have to complete an entire level (the first one, obviously) without ANY enemy dying, besides the boss. Multiple factors make this really, really hard. If you come across ANY room with floating bombots (they glow yellow and red) or the fast ground bombots (plain looking, small, dash around quickly), just quit the level and try again. These guys will ALWAYS explode, and you won't get the achievement. Every level is composed of randomized areas and enemy spawns, so you have to luck into having no bombots spawn to get this achievement. Now if you're lucky enough to get no bombot spawns, you now have to hope that the right boss spawns, because most bosses will spawn enemies who die once the boss dies... so you won't get the achievement if one of those bosses is at the end of the level. You can only get the achievement if the boss is the bull or the wall of spikes. Otherwise you're screwed. This one is tough, but it's mostly luck, so just keep at it.
EDIT: Apparently the bull spawns enemies too. He never did when I fought him, but it's a possibility. I recommend using the Egon's Pride, a machine gun that's unlocked by simply beating the first mission under the "par" time. It's easy to use, fires fast and straight, and does good damage quickly. I always killed the bull boss with it before he could spawn any enemies.
I'll actually play this game some more. It's arcadey, but the gameplay is actually pretty fun. There's lots of new guns and perks to unlock, your weapon levels up and gets stronger and you find mods for it, etc. Seems like a cool little game, definitely worth the dollar I spent on it on IGS before it was Greenlit!
