When you die, your DP level is typically reset to its level when you triggered the last checkpoint. However, you can avoid losing points by using the points to purchase an upgrade. Use this to your advantage. Find a place where you can easily obtain large quantities of DP. Do so, then purchase a desired upgrade and die on purpose. You'll resume from the checkpoint with the upgrade still in place and then you can earn more points and purchase another upgrade. Repeat it as often as you like, until you have the upgrades that suit you.

Take the sai and use the highest difficulty. Start the first level. As soon the first enemies spawn, run further into the room and ignore the enemies that initially run towards you. This will force more enemies to spawn. Run to the back of the large lobby room to fight enemies that spawned earlier. There will still be a steady supply of enemies spawning. While building combos, go towards the section that connects the lobby you are in, to the other big room. When your enemies start declining, there will be another two on the way that help you reach a 300x-combo.

Use the oven in Deadpool's kitchen to get the "I'm Expecting Company" achievement.

Interact with the following fourteen objects in Deadpool's apartment to get the "Makin' A Game" achievement.

1. The brown chair (available as soon as you are in control of Deadpool) that can be used to watch TV.
2. The phone next to Deadpool's recliner.
3. The dog behind the recliner.
4. The radio in the left corner next to the neon sign.
5. The old softa to the right of the chair.
6. The bookcase behind the sofa.
7. The toilet in the bathroom to the left of the kitchen door.
8. The sink in the bathroom.
9. The refrigerator in the kitchen.
10. The open pizza box in the lit corner to the right of the door.
11. The oven to the right of the pizza box.
12. The pump to the left of the bedroom door.
13. The computer to the right of the pump.
14. The arsenal on the right wall.

Enter the audio options and set "Dialog Volume" to "Mute" to get the "Only When He Stops Breathing" achievement.

Cook a grenade, but do not throw it until you are closer to a large group of enemies. Allow it to explode, and repeat the process as many times as needed to get the "Pull The Grenade, Throw The Pin" achievement.

Play on the Easy difficulty and do not use counters. Use grenades at the BlockBuster Boss fight to kill him.

At the start of the game there will be a tutorial on how to use your weapons. Once you are finished with the tutorial, you will be given some enemies to fight. Try to get a high combo while fighting these enemies to get extra DP. Once you have killed all the enemies, wait until you see a circle in the bottom left corner of the screen, indicating the game is saving. Once the circle disappears, pause game play and select the "Restart Chapter" option. Then, fight the enemies in the tutorial again to get more DP. Repeat this process five times to get approximately 200,000 DP. Note: Make sure the first upgrade you buy is "Greedy Perks" so you get more DP from killing enemies. Then, go down the sewer pipe, and stealth kill the indicated enemy. Next, collect all the DP tokens in the area, then buy a cheap upgrade. When you buy an upgrade, it will automatically save the game. Then, pause game play and select the "Restart From Last Checkpoint" option. Collect all the DP tokens again, buy another upgrade that costs 50,000 DP or less, and restart the last checkpoint again. Repeat this process until the upgrades costs 75,000 DP or more. Then, pause game play, select the "Restart Chapter" option, and get more DP using the first method by fighting enemies. Once you have enough DP again, proceed, and collect more DP tokens. Repeat this process until you have all upgrades and weapons to start the game.
