You can find an official guide here which contains a lot of tips about the game and boss fights video walkthroughs.
Walkthrough
After you complete the game, you will start over with everything besides your high score. This walkthrough will tell you how to get all the medals and how to get over 14 million points for the high score on your first run.You'll get 10 medals (or even more, depending on how you play) by doing what this walkthrough says in each wave. There are 6 other medals which will be explained later.
Don't let the bunnies attack you. Try to keep that 4x multiplier. It's okay to get hit once in a while, but just because you know you can stay alive doesn't mean you have to. If you get hit regularly, you wont get 14 million points. Also, buy ammo in between levels. It's highly critical!

From here on, everything is plain simple, just use your money to upgrade the remaining features, such as: AIDS, Myxo, Builder and Fortify Motel, Rage. Just remember to stock up your ammo for each wave.
When you reach to the final wave which is the final boss, Easter Bunny, grab some grenades and remote grenades. Press A to throw grenade and press S for remote grenade. The grenades and remote grenades needs to be purchased too, but does not require gun to use them. Use your gun such as XM134 Minigun to shoot Easter Bunny chocolate bomb that he throws to your motel. Those chocolate eggs can be destroyed with the bullets! This will help endure the long battle! You can shoot and throw bombs simultaneously. This way will defeat the third Boss quickly, easy as pie!
Medals
If you followed all the steps, you should have the following medals: Bullet Spender - Use 500 bullets. Death to the Bunnies! - Kill 50 bunnies. Fat Wallet - Spend £10,000. Tick, Boom! - Use a grenade. Beep, Boom! - Use a remote explosive. Echo and the Dead Bunny Man - Kill the bunny man. Happy Fucking Easter! - Kill the Easter Bunny. Kryptonite That, Bitch! - Kill the super bunny. Nice Score - Get a high score of 10,000,000. Excellent Score - Get a score of 14,000,000.Which leaves us to six more medals: AAARGH! - Go into rage. Once you buy rage on the second run, let the bunnies attack you until you get rage. Sexy Ass - You might have gotten it on the first run. But in case you didn't, all you have to do is buy a costume that makes one of the characters naked. It costs three trophies, so it's fairly easy. Jim the Conqueror - You might have gotten this on the first run as well. This one's easy. Just upgrade Jim with your money until you get it. Trophy Boy - Get all trophies. Seems hard, but it's quite easy; it just takes time. The name of each trophy should explain how to get it. And most medals fall into the same group. Just keep trying! Yippe Kay Ay - Buy all weapons. Just play through the game a lot until you get enough money to buy every single weapon. Super Arsenal - This is a real pain in the ass to get. You have to get a lot of money to complete this. You have to fully upgrade everything! Every weapon and upgrade.
