The new version includes Lena's Mod once you've completed the main game.

Please note that the 1.0.0 release has outdated code and has many bugs.

PATCH NOTES: LENA'S HARD MOD v 1.2.0 

• ADDED AMMO SYSTEM! Hold TAB to reload, up to 6 bullets!
• Patched "Carson Skip", which would occur if you killed an enemy on the frame Carson would spawn
• Increased Daniel's Speed to balance the Daniel Horde attack (1.2 -> 1.8)
• Increased individual Grimes Beam particle speed to make the beam more vertical and reduce lag (2 -> 13)
